We are a week into the 4 month sleep regression. It has gotten worse each night. Last night she was awake in her crib from 1230-230, was happy for the most part and then got herself to sleep. She woke up 15 minutes later and would only sleep with us or in our arms. She no longer goes down easily when drowsy. Her naps stink too. I talked to our pediatrician and she gave us the green light. She suggested training for the first half if the night and if she gets up after that to nurse. I worry our little one won't go down after that but we'll see. Any words of wisdom?
