So my little one is going through his four month sleep regression and I was just wondering if anyone could help educate me a little. What I've been told about it and what I've researched in my own has taught me that it's a permanent change to his sleeping pattern and it can be the start of teaching baby how to sleep without the aid of mum or dad. However my son can already fall asleep in his own and I was just wondering how the sleep regression would affect that? Will he still be able to fall asleep on his own or will I have to teach him again? And will he gradually go back to sleeping longer stretches or is that something I'll have to teach again too? Just curious.
