We have four kids. My husband works three days a week and I work two and at the moment that’s how we juggle it all..
However. I am 100% default parent. No question. I didn’t choose that, I don’t think most people do.
What happens is this. You carry the baby so you’re obviously default parent at the point of conception. Then you breastfeed, so again biologically that makes you default for the time your feeding the baby. But you have a community of women around you on here and IRL, your mum, the friends you meet at baby groups, other friends with kids, and you talk to them about weaning and nurseries etc and so then you start to make those decisions too. Don’t get me wrong, your husband will hold the spoon for the weaning and do the drop-offs but will he be the one to have done the research etc? No, because you’re the one on mat leave so you have time to do it and you’re already much more intertwined in the baby’s life and biologically connected to it. And when the baby cries, in my experience the mums physically can’t leave it for more than a second or two so they’re the ones who pick the baby up and soothe it while the men finish their massive morning poo or whatever.
And before you know it, you’re the one picking primary schools because, well, you have the network of other parents who have been through this before and can advise you etc.
So whatever active role your partner plays, however enthusiastically, it’s always really you who’s going to be driving it. And that gets bloody exhausting which is why so many women I know often drop their hours after baby number two, and around we go.
I guess the question you need to be asking yourself about whether your partner is as fully on board with 50/50 is whether he’s on another forum right now, assertively asking about how on earth he can make sure that he’s properly an equal parent and how he can ensure he plays a 50/50 role in everything.
Because if he’s not, then you’re already default parent without intending to be so.
People do manage it, of course, but out of about 100 women whose circumstances I can be confident of, whether they work full time or not, there’s only one who I would consider had her husband as default parent, and he’s retired.
