MY KIDS ARENT SLEEPING HELP ME!! PPD…

This is Long, but I beg you if you have time please read and help me. I really need it. I feel like my PPD is coming back. I need advice.

My two kids used to be on a schedule and used to sleep perfectly.

My 1 year old would go to bed around 6:30-7pm and sleep through the night until about 7:30-8:30am.

My 3 year old would go to bed around 6-6:30pm (when he started dropping naps). He would be exhausted and fell asleep right away. He would wake up around 8-8:30am.

We moved out of the only home they’ve both ever known and moved in with the in-laws for a couple months. During this time their schedules were thrown off, there was no routine or structure. They didn’t have all their toys. Their rooms weren’t set up (my one year old slept in the spare room in a playpen). My MIL nagged my 3 year old so much and would shove food down his mouth that he started to cry and not want to be around her and hardly eats now. So I would just keep the kids with me in the basement and we’d basically watch by all day. Bad I know, but that was the best way for me to handle the situation at the time.

Now we moved out for about 3 weeks now. My 3 year old got way more attached to me. I literally can’t do anything. He’s always crying. He’s literally not sleeping. I put him down for 7 and he was awake until 9pm crying and coming out of his room a lot, saying he’s scared, saying he’s hungry, saying his tummy hurts, etc. Yesterday I thought maybe he’s overtired and I put him down for 6pm, he layed down for maybe 20 minutes? Then did the exact same thing didn’t fall asleep until baby 8:30? Then he woke up 6:30am crying.

My one year old literally wakes up, opens her eyes and just screams at the top of her lungs until I get her. Then during the day she cry’s and screams off and on (I feel like more than not) for attention. She always wants to be held. Her sleep hasn’t been the best either. The other night, literally every hour she was up screaming. She just may be going through some regression? But I’m more concerned with my 3 year old tbh since he used to be a fantastic sleeper (and I worked hard at that). He also

Used to go to his room while my 1 year old slept for “quiet time” which gave me time to either cook, clean, or just relax…even take a shower. That helped my mental health so so much, but now he won’t do that.

Any suggestions? I’m wondering if he developed some sort of anxiety? Idk how to handle this. I’m trying to be loving and patient, but I feel my anxiety creeping in and be getting less and less patient. I’m super stressed and anxious and beyond exhausted. I have been suffering with PPD from a traumatic birth with my 1 year old, I finally felt like I was getting things sorted out and feeling better, but now because of this (no sleep, no time for myself, etc.) I feel it all coming back and I’m scared. I just need these kids to sleep.

Has this happened to you? If so, anything that helped?
