so I’m needing some advice/tips and help with my boy, he is 18 months old and has always been a great sleeper until the past two weeks. So here’s some background info: he has a nap at 12:30 and sleeps between 1-2 hours and then his bedtime is at 7:30pm and wakes up between 6:30-7:30am. Now the problem that I have is he is currently in his cot with a pillow and duvet which I introduced a couple of days ago to see if he would sleep better with it, however that hasn’t been the case. For example he will wake up roughly around two hours after having put him to sleep and won’t settle in his bed so I pop him into mine and my husbands bed and he just tosses and turns then wakes up crying/screaming with frustration because he cannot get back to sleep. After he does eventually fall back asleep I’ll transfer him back into his bed but then this just repeats throughout the night. We all sleep in the same room as we’re not in the circumstances for him having his own room as of yet. We are left with some very sleepless night and not sure what has changed or what we are doing wrong. Someone please help 🙏🏼
