DS has always been a good sleeper. Bedtime is 7/7:30pm and he usually wakes anywhere from 6-7am. He doesn't nap in the day for the last month or two as he just wasn't going to sleep anymore when we put him down for a good shirk but we try and get him some chill time in the day. The last week he's started waking anywhere from 4:30am and we're shattered! I'm currently 6 months pregnant and working evenings a few times a week. The only change is the time of year and he's excited to open his advent calendar cause he asks for it when we go in. He also was saying he wanted a light on at bedtime and was scared of the dark but I think that was just him trying to delay going to bed and I don't. Want to make his room any lighter to wake him even more! If he's happy enough I've tried leaving him to go back to sleep but he doesn't or he starts shouting or crying for me so I have to go in and try telling him it's still night time but he just doesn't go back to sleep so I can't either! I'm a really light sleeper so the slightest squeak and I'm done for. I just don't know why it's suddenly shifted or how to move it back. Im going to give him his advent after lunch or something instead and see if that stops him getting excited about it from that angle.....any advice or anything I can try would be amazing thanks.
