Going through the same I tried skipping naps and she still get up and.

Yes there’s a sleep regression at 18 months and possibly another around 2 years old. My son was doing that too, he’d stay up for like 2 hours in middle of the night. It’s temporary and you just have to stay consistent with your response. Put him to bed a little earlier if you can and wake him up at the same time each day. We never skipped naps because sleep deprivation usually leads to less sleep, not more.

Skipping naps then bed around 7:30 worked for us. If we’re behind on bed time by more than an hour it’s a fight to get her to sleep.

I might have to start skipping naps. Everyone fights all of the time, I'm so sick of it.

My son will be 2 next month and I’m going through the same yesterday he went to bed at 8/9 woke back up at 11 pm so I gave him some food, changed him and gave him a warm bottle and he went back down around 12:30/1am but other days he will wake up and stay up till 4:30/5am so I’ll be following this post 😫

So im not sure if this will work for you guys because every child is different. But try putting them to bed earlier... i know i know it sounds backwards... but for some reason it works with my kids.
