If I remember correctly, Katie is the same age as my niece, about 3.5 months. Since they're discovering their senses at that age all things are educational. Things with different colors and textures are great.
We got our older son an exersaucer when he was about 4 months old. They're expensive, but he loved it. It's nice that they can sit upright in it and it has a lot of different toys on it. I'd put it in the kitchen so he could sit and play while I cooked or washed dishes. We got a lot of use out of that toy. I'm looking forward to getting it out of the closet in a few months for my baby to use.

Here is a picture of my older son, Nathan, at 12 weeks old. I think this was his first time in the 'saucer.![]()
