Hi mummies my baby is 2 years old but just 10 kilos. How can I increase her weight? She’s a very picky eater ?

If she's on track with her weight gain, I don't think you should be too worried. Kids are usually a little fussy at this age. Let her try a variety of food and even food the rest of the family eats. Her tastes must have matured and she must probably have outgrown her baby food.
