One month old sleeping all day

Liz

Indigo has been sleeping most of the day today. He’s a month and 2 days old. It’s been 3.5 hours since he last ate, he’s been sleeping for about 3 hours, and he went a 3 hour stretch this morning. He’s gained about two pounds over his birth weight, and has plenty of dirty diapers. Am I in for a rough night?
