Nighttime diapers???

So my LO is 5 months and this week she has soaked through her diaper and onto the crib twice. We even bought these diaper pads from amazon and every morning it’s soaked and either coming through or about to. She unfortunately eats around midnight and again at 4/5 am and sleeps another hour. I don’t change her bc I’m scared she’s going to wake up too much and not go back to sleep!

Why don’t they make overnight diapers in smaller sizes? She’s size 2, but we put her in 3’s with the pad and it’s helped a little.

Any advice? These diapers say they last 12 hours, not for my babe!
