I hear this mantra from a relative, food before one is just for fun. Except I do not think it is true. Yes before one babies should b3getting the majority of their calories from milk. But from six months old babies usually need their iron levels boosted through food. Sure you can give supplements to do this if they will not eat. But surely the fact they can no longer get everything they need from milk, shows that babies have been designed to eat some food for six months old? And that food is not just for playing with?
