I need some help mama’s. We transitioned our 15 month old into his crib in his room about a month ago. He did well for the first few weeks and was sleeping through the night. Last week he started waking up in the middle of the night, crying and inconsolable. We can get him settled back down but we can’t get him back to sleep in his crib but will go back to sleep in his pack n play in our room. Saturday night he woke up in the middle of the night, I tried to talk him through it over our monitor with no luck. Next thing I knew he had his leg over the rail. he did the same thing last night and tonight. We have dropped the mattress all the way down and he is still able to get his leg over the rail. He hasn’t figure out how to lift himself up yet but I feel it coming. How do I nip this?
