Our little one (18mo) is getting so worked up through the night she's being sick.
We do bedtime every night around 7pm, she takes a bottle of milk, read a story and a quick song (both by our almost 6yo) and straight into bed. We leave the room and she'll settle fine. There will be a couple of cries to find her dummy between then and (roughly) 1am, but is generally fine.
When she wakes at 1am we change her nappy, given her some milk and back in bed. Again she settles fine, but 15-30mins later she's awake and screaming.
We have tried keeping her in bed and lying her down constantly or telling her to lie down, tried taking her out and cuddling up in a chair (still in her room) But the screaming goes on and on until she is sick, this then upsets her more. She'll someone settle for 10-15 mins, but will then start again.
It makes no difference if it's me or my partner, we normally try to take turn about each night, but it's getting to the point where we're swapping in the middle of the screaming because we, ourselves, are get frustrated and upset. We have no idea what's wrong, why she's this distressed.
Please help.
