Baby not taking enough weight ( in my opinion)
So baby is a boy, born 9,4 pounds and about 21.5 inches.
He is getting 5 months next week and he is a really active baby, ne laughs a lot he moves a lot ( in his jumper or even when he lies down).
He doesn’t site yet, but when we hold him on the ground he can also stand by himself and he can turn over np.
So he seems healthy
The issue is that he is only 15,1 pounds after 5 months so only took 6 pounds ish since he was born.
He drinks 7 ounces of formula per 3h, in the morning and at supper we add 2.5 teaspoon of cereals ( and he eats them all) we mix it with formula
And for dinner my GF gives him sweet mashed potatoes ( and formula) and he’s really loving them
He usually goes to bed around 7-8PM and sleeps till 6-7 AM, please note that he almost doesn’t sleep during the day as he refuses too unless we go for a car ride
But I still feel he doesn’t weight much, he still uses sizes 2 diapers.
Doctor says he seems fines and not to worry, and familly says well he’s tall so it’s kinda normal and that a baby that smile and play is a healthy baby, but I’m still a bit worried
Should I be?
