We bought this toy V-tech sit to stand walker at once upon a child. It doesn't lock well. Our DS was using it learning to walk and fell. He busted his cheek open on it. Their original plan wasn't good. I found out there lots of accidents using it.
These are 2 pics of it. The top tray comes off and change positions.
We wrote them and they sent us the new version which very stable and a lot better. This is the new version. The front detaches so they carry just that part.
Just wanted to let over know in case.
