Brandon loved this piano gym his Uncle Matt and Aunt Emily got him. I highly recommend this if you have a boy. They have a lot of energy and those dangling toys alone don't seem to do too much to keep a baby's attention. Having the piano keys to kick was what excited Brandon.
A big ass mat. Those tiny little ones are pointless. If your child is big enough to need a mat, he's a big enough to need a large one. They roll over like crazy and one roll would land them off of a little one. We keep our mat in our living room. Tacky? Yes. But useful? Yes.
At this point he was too big for the piano gym, but still needed to get his energy out. A bouncer is perfect for this. We got him the Little Einstein one because we are brand loyal, but he loved the Jumparoo at daycare even more.
Brandon loves to pull himself up and bang on shit. So his new obsession is his activity table. I got this at a consignment sale when he was just two weeks old, never thinking he would play on it this early. But he crawls to it from another room.
