Hi allll, recently been on holiday with our friends and their baby, our babies are 4 months old and only a week apart! Friends baby sleeps all night, sleeps when he is put into his crib but also has a dummy. My DS doesn't have a dummy, doesn't sleep through the night and when places in crib and night time he grunts and sometimes cries until he's rocked to sleep (occasionally our himself off) not really sure what I'm getting at but do you think it's easier for friends DS to settle better with a dummy? Does it take babies without dummy's to find a way to settle themselves longer??? 🤔
