U can start with rice cereal.. cerelac brand or friso... I mix 1 or sometimes 2 tablespoon of rice cereal (mix with water accordingly like puree)+ 60ml of my breastmilk for a start and put it in his bottle..😅 then slowly I gave him rusk(can order from shoppee HEINZ brand)... and also cerelac rice cereal.. the green one...spoonfed..also I gave him organic teething biscuits.. Anyways, before Ur baby turns 1, it's ok as long as Ur baby is drinking milk well.. do it when he's ready or showing signs of interest in food.
Have you tried baby rice cereal? My kid prefers rice cereal over purées probably due to the taste.
