Pretty sure dd is going through the 4 month sleep regression (turned 4 months yesterday) At the moment we are rocking/ feeding to sleep and tbh I dont really have a problem doing this. The issue I have is she is taking 30 minute naps and then getting overtired come evening because she's not had enough sleep. Do we need to sleep train for her to be able to connect sleep cycles or will this just come as she gets older? Also did anyone find their DC started putting themselves to sleep without sleep training; basically if we don't sleep train are we going to have to help her to sleep for years?
