I'm not sure if this is the right section for this. My daughter is about 14 and 1/2 months old. She's only 18 lbs. 3 oz. and about 30 inches tall. I still have her in the rear facing infant carseat cause she's supposed to be a year old AND at least 20 lbs. to go into a forward facing booster seat. But since she's older and taller, she is obviously uncomfortable and wants to be sitting up right. Would it be bad to move her up to the front facing booster since she meets all of the requirements beside the weight?
