Re: weening my 5 month old
ITA with all PPs. DD1 was only on BM for two months, and she didn't sleep through the night until 3. I hated waking up in the middle of the night to make a bottle or two or three. Now, with DD2, we cosleep (we didn't before I found out about how much easier it is to nurse while cosleeping) and I barely wake in the night and I'm so much more rested.
I think it varies from child to child and just because your others did, doesn't mean that it will be the case with your 5mo old.
