To actually answer the OPs question, and not pac's...
My Toadstool grows somewhat slowly - she hit a 3.5 inch width (across her back) at around 8 months old. She is now almost 4 inches across, and is a little over a year old. I just feed her crickets, and she has had a pinky mouse, but she didn't seem to like it much.
As long as your frog seems happy and healthy, I wouldn't worry about it. I have an albino pacman frog (Hedea) who actually likes being handled. I have to handfeed her occasionally, as some times she's just like "You don't actually expect me to move, do you?". So I feed her, pour some water on her to give her a bath, and pat her a little bit before putting her back. She seems to like everything but the water pouring.
