Dd is going through the 4 month sleep regression/ coming out the other side. She can fall asleep on her own and self soothe to sleep. The problem is she is still only taking 30 - 40 minute naps. Occasionally we get a slightly longer one. I wouldnt mind but its making her overtired and cranky come the afternoon and evening. I've tried everything from going to her just before she tends to wake to push into the next sleep cycle to making sure the room is dark and quiet but nothing helps. The only thing that sometimes helps is if I get her out of the crib once she wakes after 30 minutes and let her sleep a bit more on me but I don't want to be getting her into bad habits and it's not really a long term solution. TIA
