Hello sir, My girl has completed 8 months, but she still weighs on 7kgs, height 72 cm (birth weight 2.6 kg). Every days: 3 meals (gruel with meat/fish/egg and vegetables and 1 spoon of kiddy oil), 600 ml milk (240ml breastfeeding, 360 ml formula milk). She can crawl and has 3 teethes. is it normal for her? is she so small or rickets? how can i improve her weight?
