What a cute little girl ? How old is little charlee? If she's too young, she may not be ready for the jumperoo or to fully explore her toys. I know my lo needs lots of encouragement and when she does make the attempt to grab a toy and play which she just started doing, they I make a huge deal about it.
I find the gymini a godsend, it encourages them to play and teaches them cause and effect. I put her under there for her diaper changes since day one and she spends lots of time kicking and swatting. Exersaucers are good. Jolly jumpers are lots of fun when there about 3 1/2 months, before that she didn't seem to know what to do. Really light rattles that are easy to hold are great, anything heavier or cumbersome don't work out. As for the flashy light up toys that are complicated, she has not interest in them yet, I think that's more about six months. Other stuff we do, sing wheels on the bus, itsy bitsy spider, this little piggy, patty cake. I read books to her. She watches baby einstein videos from time to time. I try and teach her to roll over and spend hours on the carpet with her!
Mirrors are great too, mobiles are wonderful! Wow .. I got carried away!
Anyways, hope that helps, once again her age plays a big factor. Have fun!
