other things (am i doing 'this' right, should i do it 'that' way?) that worry me.
Honestly, there is nothing to worry about. They need to be on your breast (or just on you if bottle feeding) all the time, and kept clean! That's it. That really is about it. Smiling, chatting, cuddling, skin contact, access to the breast (or bottle) whenever they want it is about it. Anyone who tells you otherwise has an axe to grind, is interesting in 'training' (and although I don't want to be judgey -- PLEASE don't attempt to train a newborn) infants.
Riding the chaotic first weeks through and having the baby close by and sleeping when they sleep and not worrying about routines is for many (I'm by no means saying all) the best way to cope with the upheaval.
I'm pregnant with a second and worry about how to juggle it but fully intend on co-sleeping with this one as well (you don't have to if you don't want to but it is best to have the baby in your room at least) as it's the best way for me to get rest and the best way to establish a good breastfeeding supply.
I'm also intending on tandeming (can you imagine what GF would say) as my 2-1/2 year old hasn't given up feeding.
I actually think if I'd gone ahead and had the maternity nurse it would really have interfered with how I worked out how to respond to my child. Too much 'noise' from a supposed 'authority' figure (and honestly, they don't have the answers, no one does, only YOU do) and you may even feel it goes against your maternal instinct.
But then I have gone against every 'nannying' style technique, training, practice and looking back the advice from midwives in Singapore (can be old fashioned) was plain wrong -- particularly about breastfeeding.
Cutting to the chase. You may feel you need advice. That's fine. You may feel overwhelmed and welcome some direction from an authority figure. I can understand that, and certainly felt it myself before I gave birth.
But you may or you may not) feel irritated, patronised and crowded out by having effectively what is likely to be a (bossy) stranger in your house. I even felt crowded and irritated by my own mother being there and could have done without any visitors.
I have a few friends who have multiple nannies, night nannies etc and they all found them useful, but then they've taken a very different parenting approach to mine -- which I fully accept isn't for everyone.
If it does make you feel calmer to have something in place, I'd go for it. You can always cancel!
Very best of luck. But you will be fine.
