I think its time to accept that C hates the bassinet on her uppababy vista stroller. I'm deciding whether to get the car seat adapter so I can use it with her car seat, or the infant insert for the toddler seat. I'm assuming using just the toddler seat right now wouldn't really work yet? She is 12 weeks, a little over 11 pounds. How long did you use the infant insert if you had it?
