Choco powdered milk for toddler

Hi Mommies, My daughter is turning 3 na soon and exclusively breastfed sia up until now. Malakas naman kumaen. Hindi bumibigat ang timbang nia, hindi ko alam if dahil ba nasa lahi na d naman tabain both sides namen ni H or dahil sa sobrang kakulitan nia. 🤣 Right now naglalaro lng sa 10-11kls ang timbang nia. May vitamins sia up until now Pedzinc, Taurex and Growee. Sabi ng mga kamommy ko na mabilis makapagpataba mga powdered milk. Kaso ayaw nia ng mga powdered milk, pero yesterday before night time and earlier this morning we tried giving her Bear Brand Choco na milk and Birchtree Chocomilk powder nagustuhan nia. So now i'd like to ask pano po ba serving ng ganto? -is it everytime na manghihingi sia? -is it kasabay lng ng meal time nia (breakfast, lunch and dinner)? -is it one in the morning, one before bed time? And nilalagyan pa po ba ng sugar un? Sa cup lng sia nainom, ayaw nia ng bottle. Thank You po! #pleasehelp #FTM #advicepls
