My baby is 5 month old, i think she does not take enough breastmilk due to playing nature and i tried every way but she does not taking enough. Due to less feeding she cries every 1-2 he for feed but again same thing happened. She is playful and peeing enough but not gaining weight . Looking thin as well. Last month she gain only 2.5 kg. Should i start semi solids for her weight gain or should i give external milk to her. Breast milk supply is also ok. Plz suggest
