My baby is 6 months 17 days old. He still cannot sit as his backbone is not that strong yet. He is still not chubby like other 6 month old babies though I have started solid foods for him. He weighs just 6.4 Kilos. Is it normal? Also can you recommend few foods that can increase his weight.

A. Hello mom babies tend to double their birth weight by the age of 4 to 6 months and then triple by The age of one year . The bone as they grow tend to get stronger .. babies by now can be given solids such as porridge made with ragi , suji , multigrain mix , rice and dals , or kichidi , curds , ghee , steamed vegetables or soups or fresh fruits or juices etc
