My LO finds it really hard to fall asleep and will only drift off if she is being bounced or rocked. She is only 3.5mo which is know is still super young but she is getting really heavy and I don't think my back can take it anymore. I would love to be able to help her to self soothe and I know that this is every parents dream and doesn't easily happen but I'd like to try to help her to do it. Does anyone have any advice as to how to start doing this or had success in doing this? Because she finds it so hard to fall asleep I worry that she will fall behind on sleep and get overtired. It has taken me a lot of effort to get on top of her naps already and I don't want to ruin this....
