When people see you struggling with a heavy load, they don’t ask if you’re doing an awesome job or exceeding all your expectations, or if carrying heavy loads comes naturally to you – they say, ‘Can you manage?’

I think there’s a lesson there for all of us.

As a dad, and an autistic dad at that, I want to be the best parent on the planet – guide, teacher, confidante, protector, therapist, playmate, master and friend. I want to be friendly, understanding, patient, relaxed, calm, tolerant, respected and in control. I’m pretty sure that’s normal – no parent thinks to themselves, ‘Damn I wish I was worse at this than I am.’ But where I possibly differ from many is my rigid, black and white, all-or-nothing approach to the subject.

You see, to my way of thinking, if I’m not the best dad in the world, then I must be the worst; if I’m not excelling, then I’m failing; if I’m not winning then I’m most definitely losing. My benchmarks, my expectations and my standards are set so high you need oxygen and ice axes to reach them. This is unrealistic, and I know that, but it doesn’t stop me striving for greatness.

Up to now, this hasn’t been much of a problem. There have been trials and hardships, sure, but every step of the way I’ve overcome them. A bit of perseverance here, some tender loving care there – all it required was patience, endurance and a sense of humour. Simple.

Not so now that she’s hitting two. This terrible toddler stage is something else entirely.

Everything that took minutes before now takes hours. Everything that once was easy is now like quantum mechanics. And everything she used to do willingly has become a clash of nuclear powers that leaves only devastation in its wake.

Bedtime, for example. I used to put her down, read her a story, and that would be that – maybe I’d have to stick her back under the covers a couple of times overnight, but nothing more than that.

Now it’s like carrying a hissing, spitting baby tiger up the stairs, trying to avoid getting your eyes scratched out while enduring a barrage of feral, bestial roars that befuddle your senses and threaten to burst your eardrums. You put her down in bed, and she kicks off the covers and is at the bedroom door before you can escape. So you fight to lie her back down, and you reason, threaten, beg, cajole and finally bribe her with a story until she’s finally quiet and allows you to leave.

Three seconds after you close it, the door flies open and she hangs over the stairgate screaming blue bloody murder at you, as though the sky is falling down and you’re the one to blame. You hide in your bedroom, wait a minute and then pick her up, against her struggles, put her in bed, against her screams, throw the covers over her and race to the door.

And then the whole thing repeats.

It’s like being trapped in Tartarus with a cruel and unusual punishment picked out exclusively for you. Two minutes, three minutes, four minutes, putting her back in bed each time only to have her wrench open the door behind you and claw maniacally at the bars. Five minutes, six, seven. The screams descend into choking splutters, snorts, grunts, growls, a demon in your midst.

Until that wonderful, horrible moment, hours later, that she’s all cried out and sits on the floor like a dejected prisoner, rattling her dummy against the bars of the stairgate locking her in her room. And you sink to the floor yourself and you slither across the carpet to the stairs, lowering yourself inch by inch, praying they don’t creak because at the slightest sound she’ll start up again.

And you slink away and fall on the sofa, and you feel like bursting into tears because you’re battered and bruised, it’s all so hard and you can’t take it anymore.

And then she starts screaming again.

Unbelievably, the days can be worse. For the past three days, my home has been a war zone. The house is a mess, the floor covered with toys, and I decided that enough is enough. I told her she couldn’t get out any more toys, or watch Peppa Pig, until she had put her wooden blocks away. Two-and-a-half hours later, having screamed, cried, shouted, attacked me, laughed, giggled, batted her eyelids, hugged me, pleaded with me, thrown herself into the walls, thrown the blocks, hit me with her doll and overturned half of the furniture, she put the blocks away.

Did I feel jubilant, triumphant, victorious? Hell no. I felt emotionally raw from the hours of abuse, fighting to stay calm as she pressed every button and tested every boundary. I am the mountain worn away by the sea. But I consoled myself that the next time, it would be easier.

Yesterday, I told her to put away her wooden blocks before we went to the park. Three hours later, on the verge of screaming and crying myself, she put her blocks away. I won. At the cost of my soul and my sanity.

Today, to be fair, it only took one hour. But who knows how long it’ll take tomorrow?

I’ve never really understood the idea of picking your battles – I’ve always been of the opinion that if a principle is at stake then you attack it wherever you find it – but I’m discovering that flexibility in parenting a toddler is a must. After hours of fighting over the wooden blocks, when she started taking the DVDs out of their cases and putting them back in the wrong ones, you know what I did?

I pretended I didn’t see.

I’ve drawn a line in the sand, nailed my colours to the mast – the wooden blocks are the issue on which I hang my hat. If I can master this one thing, then I’ll deal with everything else, but I can’t do it all at once and I don’t have the energy or the emotional resilience right now to be master of all things.

Because the truth is, while I might want to be good at every aspect of parenting, to excel and overcome and be the best damned parent in the world, I’ve realised that in order to survive raising a toddler you have to lower your standards, relax your ideals and temper your expectations, or you’ll go crazy.

And that’s okay. Like the man with the heavy load, nobody is asking if I’m excelling – they’re asking if I can manage. And yes, I can.

That’s the lesson I take from this week – I might might want to conquer Everest, but setting my sights on Kilimanjaro as a more realistic alternative doesn’t make me a failure as a parent, does it?

Does it?
