Since after we've made it past the 5 mo mark, solids have been a lot easier in getting most of the food to stay in the mouth. We've tried rice cereal, oat meal, apples, pear, chicken, sweet potato and bananas. Since Eliza, I love the Munchkin brand spoons for this stage in eating. The bumbo tray is a new addition and will try and transition him to a space saver chair later on as Eliza still uses her high chair as a booster stool.
There are many times where it seems like I can't shovel the food in fast enough. As I am sure I will be a little sad, I do look forward to the self feeding phase.
