Congratulations! And thank you!!
The mirror can be found at any baby store. I'm not sure if you have a BabysRUs in your town--they are the baby version of ToysRUs. But I've seen them in stores that cater to baby safety as well. We bought 2, one for each car, and they are great to have. The MINI mirror is on the small side to see the reflection. I need to stretch a little bit from my normal driving position to see the mirror. It's not hard, but does require a bit more effort than just looking into my rearview mirror. This way I can see if he's sleeping or wide awake.
He's around 11weeks now, and doing great. He's a lot more vocal, and is sleeping around 5 hours a night now. He's able to grasp things. In fact, he's strong enough to sit propped up against my MINI seat. I took a picture of him on June 5, as seen here, and I needed to hold him up. Now about 1 month later, he's sitting up in the same seat without any help.
I'll have to post that pic later, but he almost looks the same!
