Hi. My 4 month old son has been waking every 2 hours during the night since he was 16 weeks (now 20 weeks). He will just stir then go back to sleep with a little breastfeed. We cosleep because he just would never settle in his crib. Before this stage he would sleep for 5 hours at the start of the night, then usually another 3 and 2 hour stretches. Just wondering if anyone has had this with their babies and is it only a phase? He won't take a dummy during the night, I have tried and he is breastfed only. Thanks.
