I finally figured out how to put the seat back into the exercauser! I had washed it way before Ethan was born and stored it. Only recently did I believe he was ready to sit in it but couldn't remember how to reinsert the seat! Finally he can use it! But those little buttons that make all the noise are really loud and there is no volume control! Do you think we will be limiting time in this thing? :) He seems to enjoy it a bit though.
