Anyone still rear facing?

Jullz ☀️

My daughter weighs only 29 pounds and her car seat max is 50 pounds and she has been requesting to face “like her brother” (who’s 5) and I’m like noooo… but like would it be the worst thing if i tried it? Probably won’t do it but just want others input. She’s so tinyyyyyyyy poor thing she justwants to be like her big siblings… side note how does your little one weigh?
