Sleeping baby

You guys, I currently have a 3 month old as of today :). For the past 2 weeks my child HAS not been sleeping though the night anymore. I know some of you guys would say she’s so young she shouldn’t be sleeping through the night yet. Welllll she started sleeping from 10-5. It was wonderful. But now she wakes up at 3 and 5 to eat. Have you guys ever experience this? I know it’s probably because she maybe going through a growth spurt or just purely hungry. Just curious on how long it will last. I know some moms say their child slept through the night at 4 months. (Sorry that I’m all over the place)
