Every baby is different. Traditionally the recommendation is 6 months. Baby needs to be able to sit up without flopping down (can be supported in the high chair), and should also show an interest in your food when you’re eating. Some people may start earlier at 4 months, but if baby’s not interested so early, no need to force. Also start off with very small amounts of puree.. the mainstay of nutrition at the beginning is still milk
Can try solid from 4 months onward provided baby can hold his head and sit upright During my 4months routine check, PD give green light to let him try
