My 9 month old has successfully weaned off the bottle and is on 3 meals a day. What should I be feeding him so he has a balanced diet?

It is really important that you maintain balance between solid food and liquid diet for the baby. It is also essential to add nutritional food required for the proper development of the child. Here is a guide for you to follow a healthy diet chart for your baby, from breakfast to bedtime- https://www.healthychildren.org/English/ages-stages/baby/feeding-nutrition/Pages/Sample-One-Day-Menu-for-an-8-to-12-Month-Old.aspx
