(I promise this is not anything about the previous post)

I went to do grocery pick up this morning and my son managed to unbuckle his car seat!! I pulled over and buckled him back in and a few minutes later he did it again! I'm now terrified to take him in the car. Also he's 12m, I thought we weren't supposed to deal with this problem until much later! Any tips or something I can do to prevent this?

This is the car seat we have if that has anything to do with it

Also for any of you that we're following, my son's covid19 test came back negative 🥳 and thankfully the fever seems to be gone. He still has a bit of a lingering cough and he's now covered in these itchy red bumps that look a lot like chicken poxs:( when I talked to the doctor he said a small percentage of kids do get a mild case of chicken poxs up to ten days after the vaccine so there's that :/
