Overweight baby?

So my mom says I’m hurting my baby by feeding him his milk and says I need to cut it down, but he doesn’t drink a lot, she thinks as soon as he cries I give him bottle but no I don’t, I pick him up I walk around with him, I do tummy time, I take him outside, i don’t just give him bottle to shut him up, and his doctor cleared him for baby food so I give him some,but not every single day. He’s 19 pounds his doctor said he’s fine, he’s 4 months turns 5 this month on the 30th. Am I hurting my baby? Did I do this? Is he too big? My mom constantly talks down on my parenting but man, I believe I’m such a good mom and I’m all about my kids. But she makes me feel like im terrible. ( we buy the big can because idk saves a trip to the store lol he doesn’t go through it fast) also his dad is 6’2 and his uncles are big big boys , but my first son was big too and he stretched out and he’s skinny and tall like his dad but my mom just believes I’m hurting my youngest and that he’s in pain cus he’s too big.
