When can baby start to eat solid food?

Doctors advise to wait until 6 months. There's no significant nutritional benefit to give solids before that. Also, you may want to consider traditional weaning or baby led weaning. You can easily Google the methods and pros and cons. Personally I prefer tradition weaning as i can't bear the risk of baby accidentally choking. Start off with very soft pureed foods, e.g. steam and blend rice, potatoes, carrots, pumpkin etc.
