Awww, Hun don't feel bad. I did the same thing with my second child. My 1st was sooo fussy if I didn't hold her all the time and then my second was just in love with his bouncy seat. I swear he stared at it from across the room. They have hit their milestones at the same times too. I tried to play with him and give him his "tummy time" but it just made him angry. Stick with what works. If she's content and enjoys it you are doing nothing wrong. Wait until she gives you clues that she wants to play (and trust me, she WILL!!). Just try to talk to her as much as possible and let her know you are there. Thats all you can do. Enjoy it!
