My child growth was normal up to 2 years but after that her growth was slow down (height and weight) and her immunity was also low. can you suggest for these?

A. dear mum, what is the current weight and height of your child at the age of 2 years? balanced homemade diet is the basis for good health and immunity.baby's daily diet should have grains, millets. proteins like pulses/non veg, egg, nuts. seasonal vegetables, green leafy vegetables and fruits are important. curd, mint, turmeric, ginger should be included.
