So my LO will fall asleep on her own in her crib but it only ever lasts for 30-45 minutes. I know this is the time they transition into a deeper sleep so how do I help her achieve this? I will add I just started her in her room yesterday and she has done beautifully putting herself to sleep so she seems to do well with that. Not sure if she just needs more time in her crib to do this or is it something that they gain with age? Idk just looking for some insight or help.
