My son is 2 and obviously still in a 3 point harness car seat, rear facing. He has the Graco 4Ever DLX. I really like the seat, it’s sturdy and comfortable. However, has anyone worried about their son’s testicles after they’re out of diapers? The strap in between the legs has to be snug for the child to be buckled in properly but I’m concerned it will be uncomfortable when he’s out of diapers (which will be soon). Is this a baseless concern?
