1 month old. Slept 6 hours straight.

So my baby boy is 1 month tomorrow. This week we have been struggling with constipation/gas and sleepless nights. I would say he's mildly colicky. We switched to gentle ease formula (due to medical reasons I wasn't able to BF :( ) and his stool has softened up a lot but he's still acting like his gas causes him pain. Anyway, he slept 6 hours straight last night. The extra sleep was amazing but naturally instead of being happy I worried that his tummy issues are causing a lack of appetite lol. We just went up to 4 ounces so that could be some of it. He usually has been having 4 ounces every 3-4.5 hours. Is this normal for anybody else's baby at this age? I'm hoping he's eating enough! His weight gain is on point. He was born 5lbs 12oz and now weighs 7lbs 5oz
