My LO is 3 months old and gained exactly a pound in a 4 week span. The doctor told me to either wake her at night (she sleeps through the night) or feed her more during the day. The problem is that during the day she doesn't WANT to eat more. I offer the breast and she won't take it unless she's hungry for it. Is a pound really too low to gain in a month? How much are your babies gaining each month?
