How long is okay for a 1 month old to go between feedings. I know 3 hours is recommended but my baby won’t eat until it’s been 3 and a half to 4ish hours... when she eats it’s also only for about 15-20ish minutes. Is this okay? This has just recently become a new pattern of hers. She used to eat every 2 and a half to 3 and was being bottle fed until recently. So far her diapers have still been fine. I’m not sure if she is gaining weight because I don’t have a scale and this has only been going on for 2 days.
