My little girl is 15 weeks (17 if you adjust for due date). She is combination fed and had been into the way of waking once in the night fir a feed around 3am but otherwise sleeping from 8ish through til 7. We used to be able to bath her, feed her, pop her in her next to me crib do a few stories and then she'd fall asleep no problem. In the last week or so bedtime has been traumatic. Our otherwise happy little girl now screams her head off when it's time to go into her crib. We do the bedtime routine with no issues, but as soon as she's in the crib she has a meltdown. Twice we have managed to stroke her brow and gently shush her to sleep but other nights I've ended up breastfeeding her until she falls asleep then transferring to the crib. This usually gets us about 4 hours of her sleeping before she wakes and again won't settle in the crib. I've checked the crib mayress, sheets etc and nothing has changed or is damaged.
Could this be the 4 month sleep regression or could there be something else I'm missing? Does anyone have any advice either on how to make things better for her, or to reassure us that it's a passing phase and she won't be miserable at bedtime forever?
TIA
