Hi! My DD went through similar sleeping issues when we got back home after 2months away. I created a similar thread too! Generally the advise I got was just to persist and she will get through it! And after a few weeks she did. In the past I borrowed a rocker from a mate and she would only really sleep in that during the day! If he likes being rocked then maybe it's an idea to hire/borrow/buy one?

Do you swaddle him to sleep?
