Izzie’s first word has well and truly arrived. I’m not talking about the rather funny imitations she does – pronouncing buzzard as ‘buggered’ and beach hut as ‘bitch hoe’ – no, this is a real, bona fide, unmistakable word, used without prompting and in the appropriate context.

Unfortunately, that word is ‘mummy.’

I say ‘unfortunately’ because now that she has learnt the word, she has decided to use it in earnest. ‘Mummy, mummy, mummy,’ she says as she wanders about the lounge. ‘Mummy, mummy, mummy,’ she mutters when she’s supposed to be napping. ‘Mummy, mummy, mummy, mummy, mummy.’

This is a particularly galling word to hear when you’re a daddy, and you’re the one getting her up in the morning, or changing her nappy, or bathing her, or feeding her, or playing with her, or cuddling her, or all of those things you do that you really wish she’d be grateful for, and for which she might reward you by saying ‘daddy’. It’s hard to remain upbeat at three in the morning when she wakes you up crying, and as you try to settle her down all she can say is, ‘mummy, mummy,’ as she gets snot all over your shoulder. And it’s rather difficult not to feel a little aggrieved when you put her to bed, kiss her cheek and bid her goodnight for her to reply, ‘mummy, mummy.’

You might think she’s simply saying the word without knowing what it means, or because she likes the way it rolls off the tongue, but you’d be wrong because she knows exactly what it means. I’m not sure which came first, her obsession with the word or her obsession with her mummy, but she’s decided that mummy is the coolest person on the planet and daddy is just some guy that mummy lives with. Yes, I have been pushed aside in favour of a person with bigger boobs.

Who does Izzie want to see in the morning? Her mummy. Whose lap does she want to sit on? Her mummy’s. Whose hand does she want to hold when we walk down the street? I’m sure you can identify the pattern in this. I jokingly asked her this morning who her favourite parent is (like she’d be able to understand, ha!) – and she pointed at Lizzie and said, ‘mummy.’ Ouch. In retrospect, I’m not sure what I was hoping to gain from that question!

Following quickly on the heels of Izzie’s first word came her first full sentence yesterday – we often show her how to do something and then say, ‘Izzie do it,’ so when she was struggling to fit the shapes through the correct holes on her toy, she picked it up, plonked it down on Lizzie’s lap, and said, ‘Mummy do it.’ It was a revelation to her – now she can ask mummy to do everything!

It has been a week since this started, and while Lizzie initially rubbed it in – ha ha, she’s not saying ‘daddy’, is she? – even she’s getting a little tired of the constant, ‘mummy, mummy, mummy’. More worryingly, when I tried to kiss Lizzie earlier, the little tyke clambered up into her lap and started slapping me in the face, as if to say, ‘Get away from my mummy, you horrible man, she’s mine, all mine!’

A few weeks ago she was definitely a daddy’s girl. Now when I cuddle her she reaches out for mummy. I figure this is all just part of growing up, and toddlers being toddlers, and it’s not like Lizzie and me are in competition. Still, I’m looking forward to the day that as I close her bedroom door I’ll hear the words, ‘Night, night, daddy.’
