Help - 10 month old stopped sleeping!!

Hey everyone, my baby used to be an incredible sleeper. 7:30pm to 7:30/8am straight, 2 hr nap in the morning and 2 hr nap in the afternoon. But now ever since we lowered his crib because he started standing, it's been horrible!

Started waking up during the night, waking up at 5:30am, fights his afternoon nap like crazyy. Now it takes me 2 hours to put him down. I think its a little early for him to try to drop his second nap. This has been going on for over a week now. I still try to follow our sleeping schedule but I don't know what to do! He used to be a wonderful sleeper and now its the opposite, idk whats going on!
