DS is on 3 solids a day, he is just over 6 months. He started on 1 meal at 5 months and by 5 months 3 weeks was on 3 meals. Im just starting to introduce a dessert after dinner (apple or some kind of fruit). Most of my mothers groups bubs are also on 3 meals. Just go with what bub wants. I foudn DS was getting really grumpy and needed more food. he's also on 4 bf's and one formula a day! (and a bf or two at night....hungry boy)!
