breastfeeding frequency

My 2 month old adjusted, 4 month actual preemie finally ebf (for about a month) and still feeds every 2 hours round the clock. Is that normal? We cosleep so at night he dream feeds all night, it's not a problem but he really doesn't like going over 2 hours without eating at least a "snack". I have plenty of milk (had oversupply, got it to regulate finally) so never takes more than one breast. I can tell when he is comfort nursing and normally he really eats some, just don't know how much. Last Ped's apt gained a little less but has been consistently gaining almost 1 lb a month. 11 lbs 2 oz now....never ate more than 70ml at a time when bottle fed though. Small stomach? Helps his reflux? Just wanted some thoughts.

Normal. Breastmilk digests fast and infant tummies are tiny, so it's very common for young babies to go only 1-2 hours, or even less, between feedings. The idea that babies should feed less often than that comes from the feeding patterns of scheduled, formula-fed babies- and of course, schedules and formula are not normal for the human species!

I am sure you're tired from the round-the-clock feeding, but it really is simply normal. Tiring, but normal. Tiring, but you won't regret it. :)
