Girls, I'm writing at night. The second day the baby has been sleeping poorly at night, we're 25 months old. We fall asleep with a pacifier as soon as it starts spinning and crying. It wasn't like this before, as soon as she fell asleep soundly, she spits it out herself. Every hour and a half wakes up sometimes crying. Could it be sleep regression? Although he's still too young for that. During the day, it also doesn't work to go to sleep, it sleeps either in arms for 30-40 minutes, or in a stroller on the street long nap??
