I don’t know how old your LO is but my 8 week old is the same. I think it can take easily 12 weeks for them to get used to day and night. They are usually overstimulated in the evening and their tummy may hurt. Ive got no solution but you’re not alone. Do you have a partner or someone to hold your LO while you sleep a bit?
Sounds like she maybe getting overtired which can make it harder for them to sleep. Is she getting enough naps in the day and not being awake too long between naps? My LO has a half hour nap around 7-8 then will go down around 10 ish. I notice if she hasn’t had enough naps in the day she is a nightmare at night. Does she cry as soon as you put her down? Or does she wiggle about? X
