How much should a 3 month old be eating ?

Coco

So, my three month old Baby boy , still wants to feed every 2-3 hours 😳...anyone else?? He’ll do a long stretch at bedtime for about 4-5 hours, but after that, he’s up every 2-3 hours ...

Also wondering, this doesn’t really apply to me Bc I’m breast feeding (can’t tell exactly how much baby is feeding), but if I were to pump, how much does a three month old

need per feeding..4 ounces? 5??
