DC is nearly 18mo and during the day typically BFs at breakfast and bedtime, sometimes she will have one in the mid-afternoon if we're at home but doesn't tend to want it if we're out and about. She goes to bed at 7-8pm then will wake at least once during the night for a feed, anywhere between 11pm and 3am. I don't think she actually needs the feed and is only waking out of habit, once she's had a few swallows she seems to be using me as a dummy and sucking for comfort. She won't take an actual dummy, I've tried.
I was thinking of getting DH to give her a bottle when she wakes during the night and supervising her while she drinks it herself (which she prefers to do on the occasions she has one) then reducing the amount of milk in the bottle over a few nights until she stops waking up for it.
This won't affect my supply for during the day, will it? HV drums it in at play&stay group that it's night feeds that keep your supply going but I'm so tired from not slept a full night in over a year!
