Re: When can you safely booster train?
With my oldest she was in a booster early like 3, (didn't know any better). With my middle she didn't go in a booster until she was 7, (she has ADHD) and even now I threaten to buy her a bigger five point harness seat because she has a hard time sitting stilll. My youngest turns 4 in a month and is already 40 pounds and 3'4" and she sits in a high back booster in her sitter's car but only on the rare occasion and for short trips. She sits extremely well. So I think it just depends on the child.
