Hi- I am looking for a booster seat for my "little guy". He is a 10 month preemie (size of a 7 month baby). I am looking for feedback on any booster seats for travel, but to use very often. Toddler Bargains suggests The First Years 1. 4- stage feeding and 2. the swing tray. Grandma was considering the the 4 stage and I the swing tray. However, I am seeing lots of reviews on the FP Healthy Care booster and none on The First Years. Toddler Bargains did not rate that one. Any feedback would be greatly appreciated. Thank you and God Bless all your babies.
