I have an almost 4 year old and a 16 month old. Bedtimes and nights are horrible and I keep thinking I can't take anymore but I have no choice.
Eldest has always been a bad sleeper other than a few months when he was 1 after we did some sleep training but then he was sick for a few days and we slipped back into old habits. Youngest has also always been a bad sleeper and I haven't been able to stomach sleep training.
They share a room since youngest turned 1, it has neither helped either of them nor made it worse. Bedtimes are solo parenting as we take turns for exercise or work.
The eldest pisses about something chronic at bedtime, much worse for me than for my husband. He also still wakes in the night once or twice and we have to go to him or he comes into our bed.
The youngest feeds (with me) or cuddles (with husband) to sleep, I really want to quit breastfeeding though. We put him in his cot once asleep. He wakes mid to late evening depending on what time he went to sleep and I usually go to bed and take him with me as can't be arsed sitting in a chair for half an hour trying to get him back to sleep. So he sleeps in our bed every night. Luckily a big bed!
At bedtime I sit in a chair in their bedroom and stay until both are asleep. If I try to leave then all hell breaks loose, eldest will follow me crying and youngest will scream if not fed/cuddled to sleep. So I'm completely stuck until whatever time they go to sleep.
I haven't slept for 4 years and I can't see that improving anytime soon. The bedtimes are worse for me than overnight. It's 9pm (I'm not in the UK) and they are only just starting to settle down and bedtime started at 7pm. My husband just got in from his gym class so no dinner has been started or even thought about. I am so sick of this but have no idea what to do about it, I could cry when I hear about friends' kids who go to sleep on their own by 7pm after a cosy bedtime story. I wish I could see light at the end of the tunnel but I can't :-(
