My 9 week old has decreased the amount he’s been eating at each feeding the past few weeks. It seems like he only wants to take about 2.5 to 4 ounce each feeding, eating about every 2.5-3 hours and waking up once a night to eat. Could he just have a small stomach? Do I need to try a different formula? I read he should be eating 6-8 ounces per feeding this age. He is still gaining weight but is underweight for his age. Any suggestions mommas?

P.S- You’re all doing an AMAZING job and you are THE BEST momma for your baby!!
