Why at 2am?!

My baby is 14 weeks and just doesn’t want to go down until 2am!!! She started doing this when she turned 13 weeks, so she’s been doing this for a week already! We bathe her at 7pm, put her jammies on, nested sack, feed her, rock her and goes down by 9:30pm. However, she will wake up and doesn’t want to go down until 2am with feedings every 2 hours! What am I doing wrong??!! P.S. she is not a good napper either!! 10 minute is her time and Maximum is 30 minutes. I have no idea how SHE is functioning??!! I’m running on caffeine at this point☕️🥤😴
