I know this is a tale the world over and I shouldn't really complain but am after some advice!
My dreamy second child has until this week been sleeping 10.30pm until 7am. I know.
But this week (17 weeks old) she has started waking up in the night and won't go back to sleep without a feed. I'd take it on the chin but my older daughter wakes frequently in the night and we're exhausted. The two of them don't even synchronise their wake ups - we could live with that 
Any advice to get my dreamy baby sleeps back?
