My 18 month old has never been a good sleeper, but did sleep through the night for a few months and it was bliss. For the past few months though she's been up 2 or 3 times a night and I'm struggling to cope. She seems to always be teething or ill. We've got in the habit of giving her milk in the night to go to back to sleep, and now she won't go back to sleep in the night without it, though she does fall asleep on her own at the beginning of the night and for naps.
Any tips? We did controlled crying when she was 6 months old but she's now much more persistent and loud, and I feel awful leaving her to cry.
Has anyone managed to get a toddler to sleep through the night?
