Hi,
When my son was 6.5 months he was on 3 solid meals a day. But this is partly because he started on solids at 5.5 months.
Now at seven months he has cereal and yoghurt for b'fast; meat, vege and fruit for lunch and similar for dinner. He has what we eat minus salt, seasonings, sauce etc.
Am breastfeeding so he feeds four times a day. But he isn't always interested in milk everytime.
