Baby will not sleep in her crib second half of the night.

The past two weeks our five month old refuses to sleep in her crib at night.

We put her down from 7-8 and she will sleep soundly in her crib for about 3-4 hours uninterrupted.

Once she wakes up though it’s nearly impossible for her to go back down in it. She ends up sleeping on me or my partners chest in the nursery recliner.

I feel like we’ve tried everything- heating the crib mattress with a heating pad, putting her in a different sleep sack, etc.

Has anyone else had this issue? What did you do?

(Also please don’t tell me to check out the sleep train Reddit…they are annoying over there with their precious little sleep guide)
