I read the range of parenting your new baby books, from She Who Must Not Be Named to Dr Sears.
From across the board, they can be equally proscriptive, limited and antifeminist. Personally I found Sears liberating because he at least gives you permission to let your baby decide when it is going to be fed. Also there is a lot of equation between being a 'good feminist' and 'going back to work as soon as you can walk'. It's a bogus equation, but, you know, you're vulnerable, isolated, haven't a clue what you are doing etc. It depends what your personal poison is, innit? Some women worry that they aren't earth mothery enough, some women worry that their earth motherlyness is masking a desperate need to keep them dependent. Just read any discussion about full term breastfeeding if you need any of that poison in your life.
I think the problem with parenting advice is that it comes from a patriarchal society that treats women like they need to be monitored and regulated and are in danger of killing their babies. My midwife tried to convince me I would kill my perfectly healthy newborn by failing to wake them for a feed. When I asked how often newborns died because their parents haven't woken them, she told me it happens 'all the time'. What bullshit.
At least Sears seems to value the actual processes of being a mother and isn't insisting that your feelings of wanting to be with your baby are a huge indication of the way you are failing as a feminist. Agreed, you can use what he says to make women feel shit about wanting to have a bath on their own. But that's the patriarchy innit? If womanhood didn't feel like such a fucking minefield, if being a mother wasn't such a public process that everyone feels they have permission to critique you on, nowt Sears could say would bother you.
Everything ever written about how to care for your baby can be used to make people feel shit about their parenting. I reckon that's because making women feel shit about themselves is a crucial mechanism of the patriarchy. I think you have to keep that in mind when you are reading baby books. You have to keep in mind that you are a grown adult who is in the actual relationship with the actual baby, and it's likely that you will be able to figure out what to do because, you know, you aren't an effing idiot. It's one of six options: eat, sleep, chat, soothe, change, take to the doctor. You're allowed to get that mix wrong until you have a bit of experience with that baby. Any time that you are feeling like an idiot, you can chalk that feeling up to the patriarchy and get on with your life.
