I assume you mean something like
these?
Personal opinion: They are an option but I am not a fan of them. They work but I don't like how they raise your center of gravity. Plus the child will probably move around some which can throw off your control of the bike. They say they have a weight limit of 50lbs. or so. But at that weight your child probably won't be comfortable for very long. A trailer can handle larger kids than a seat. They also are more comfortable in that they offer more freedom of movement for the kids without affecting bike handling.
The child seat might be a good stopgap option until your daughter can ride on a TAB. It would likely be cheaper than a trailer.
Look for either the seat or trailer in the used market. I saw a Cannondale trailer in very good shape for $120 this AM.
Good Luck.
