My boy has started doing this! He used to be dead to the world when we put him down haha. I now put him down and lie there and rock the next to me and sssh him and he eventually drifts off again. If you haven’t already then try that :)
Hey! Babies go through a sleep regression at 4 months old, it’s totally normal. Now might be a good time to think about sleep training (if that’s something that you want to do) and getting baby into a routine will help. It’s a phase they go through! It’s more of an attachment thing rather than the next to me. Xx
