Worry about my daughter’s weight

She es 31.15 inch tall and she weights almost 20 pounds, Dr said she is under weight but she thinks it’s because she is growing fast and she is a busy baby. Should I try to give her more food? She’s drinking Enfagrow twice a day and dr said that maybe I should use whole milk instead of water to make her milk. She poops a lot too ... like three or more times a day ... so Idk she snacks all day too. If I try to push more food to her she spits it out 🤷🏻‍♀️. She does eat lots of fruits and veggies during the day and not so much carbs, cheese and yogurt too.

Any healthy snacks ideas?

Can you show me pictures of what your 1 year old babies are eating right now for lunch and dinner?

Thank you!!!

Does she looks underweight?
