A high chair is meant for the purpose that the baby can safely and neatly consume the food if he is not able to sit on their own. Once your little one can be seated all the time without falling down, you may think of joining your baby with you on the table on a normal chair.
At least, baby ages from 12-15 months should use baby feeding chair. Safely strapped in the High Chair is the better choice. If your baby’s growth is quite slow, you can carry on with the High Chair to 2-3 years
