2 year sleep regression

I really really really hope this is the last sleep regression for my june baby. He turned 2 last week and ever since he doesnt want to go to sleep or take a nap. Wakes up multiple times at night crying. I have a 3 month old who sleeps SO GREAT, that makes it even more frustrating..

Who else is in the same boat or went through it already? How long does this last (pleaaaaas say no more than a couple of weeks🤪)

I can deal with the tantrums etc but this sleep thing évery time... it’s exhausting
