I was looking through my book last night and wondered what it had to say about my booster seat (high chair, not car). It only says that boosters are mentioned in the Toddler book. As a cost and space savings, we only have a booster seat. We've been using it for 3 months, since DS was 5.5 months.

We didn't feel we had the room for a high chair, so we got the Infant-to-Toddler Reclining Feeding Seat by The First Years. It is great, since it just attaches to our kitchen chair.

As I looked up the seat on The First Years' site, I noticed that it is a Toddler's Bargain best buy, so I guess I picked well. I wasn't ready to buy the Toddler's book when DS was only 4 months old though. Maybe you could include some reviews of boosters like this one in the Baby's Bargains Book.
