My 10 week old absolutely loves this gym. She is totally entertained by this gym when she is laying on her back trying to grab the toys. She loves looking at the mirror at herself. The toys are all removable and the mirror also works in her crib. It includes a little pillow for tummy time too. Sometimes she stops playing with the toys and just looks at the monkey and starts smiling. She loves this toy! I'm giving 4/5 stars because the toys have to be on a certain way to be able for the child to see the front (design) of the toys. Only one toy has a design on the back that is interesting for the child to look at.
