Sleep upheaval

Okay so my daughter is 5 months. She went through the dreaded sleep regression at around 3/3.5 months old. But since then, she just does not have a sleep schedule that she sticks to. Some nights she’ll sleep in 7/7.5 hour stretches and others, it’s like 4 hrs then up to eat, then 3 hrs. Or sometimes it’s every three hours. Granted, it’s better than every two hours, which she did in the regression phase, but it’s always hard to gauge what the night will be like. She’s always ready for sleep by 8-8:30 pm. I just don’t know if she’ll ever pick a schedule and stick to it!!!
