I've heard stories of babies who comfort feed at night being like that for a long time until you start weaning them off night feeds. I suppose it's hard to say whether she needs the extra milk or is just waking for comfort or out of habit. Hopefully it will all happen naturally. I have read they should definitely be sleeping through by 4 months
Are you reading evidence based information?
Or are you reading forums and listening to anecdotal information.
None of that paragraph has any truth in it whatsoever.
I know your tired OP, it's exhausting having a newborn, but you are focussing on the wrong area to improve the situation.
Why aren't you sleeping in the day? You have no other children, nap when baby does?
Why is your DP/DH not taking some night feeds? Sit him down and plan a night this weekend that he does. Either sleep in a spare room or go to a relatives so you get a whole nights sleep?
You've mentioned family, who helping you during the day? Can you get a break for the afternoon
You need to look after yourself. But nightweaning isn't the answer at 10 weeks, 16 weeks and I would argue not even at 12 months old (others reduce night feeds from 6 months, in conjunction with weaning on to solids)
Ill find you a link to read.
