BabyTrend Hybrid SI 3-in-1 Discussion
We’d primarily suggest [the Baby Trend Hybrid] for budget-conscious families who are willing to invest the time required to install and use the seat properly. The Hybrid is a mix of pros and cons... the front entry installation method can confuse even the most seasoned CPSTs and the harness weight limit of 50 pounds means some kids won’t be booster ready before they outgrow the harness.

What do we think of the Baby Trend brand?
Trust us, it's not the seat you're looking for..no matter how great it looks. It's the biggest PITA I've ever come across to install... She has a fairly short to average length torso... so, nearly any combo seat out there will fit her for awhile, except the cheapest Cosco seats and the Baby Trend (top slots aren't that tall). I would take almost anything over the Baby Trend though!
