In recent weeks shopping with my son was a real challenge. Barely 10 seconds cart and he stood on the child seat !! I have again properly seated him gabŽs course huge protests. I could never take your hand from him and have constantly forget half while shopping, because I was too distracted. The same problem of course in high chair: Ruck Zuck is the klleine husband and I had constantly need to keep him fast enough. BUT: with the belt no problem more !! It can be even the fallen without nagging and now sits peacefully everywhere! Simply ingenious = ingeniously simple !!!
