Co sleeping

I co-sleep or bed share with my almost 4 month old and have since day 1. I absolutely love it and the bond and it makes breastfeeding easier. I nurse her to sleep everynight but lately she will only sleep if i am directly next to her and facing her. I know its a comfort thing and i know shes only 3 months old but i literally cant even turn over or she'll wake up. It's not that big of an issue to me but I'm just curious if any other mamas have experienced this and how long did it last or any tips on how to help baby sleep better?
