Poor weight gain 😢

My LO is EBF and the past month or so he was not gaining too much weight. He was born 7 lbs and 7 oz. He gained 1 lbs or so the first several weeks and then the gain significantly slowed down. He just recently got passed 10 lbs at 3 months ( based on my home scale 10.2) which goes up and down by day ( yes, I’m paranoid and weight him everyday 😢) Doctor was not super concerned at his last visit since he was like that already at 2 months but I worry still. He eats on demand and eats at night at least 1-3 times. He becomes content after he eats and doesn’t seem hungry. His development seems normal and he seems a pretty happy baby most of the time (only cries when wants food or tired). I’m so disappointed and would hate to stop breastfeeding :( sorry for venting.
