Hi Not sure if I can help much because what I did is not for everyone but I used to lay down on my bed with my DD and she would play a little then settle down and I would rub her back or stroke her hair until she went to sleep. She could climb on and off our bed safely though, however when she was asleep i would put a pillow on the edges of the bed in case she rolled but she never did. some people dont like to do that as they think the baby will need you all the time but it didnt affect any other routines for us it was like she knew that was her afternoon nap routine. If you ask me anyway it doesnt matter how they get to sleep just as long as they do get to sleep lol.

otherwise it could be a little bit of a phase for her, let her go and you might find in a couple of days or weeks she might go back to her previous routine, sorry I couldnt help much.

Good luck xo
