Hello Doctor when my baby's 5 months old she is supposed to be gained 6 kgs since her birth weight is 3 kg but her weight is 5 kg when she completed 5 months and we consulted doctor for that so the doctor gave iron and multivitamin syrup. after having those my baby gained about 600 grams within 2 weeks but after that she is loosing weight now her weight is 5.3 and her age is nearly completing 6 months in 9 days . i am concerned about her weight loss , should i consult doctor for this or shall I start solids ?
