dd3 is 4yrs old, weighs 16kg and has about 2cm lft of height room in her car seat. she is in a britax eclipse, and i know she needs to go into a high back booster soon.
roughly how long, will it take for a 4yr old to gain 2kg?
also does anyone know of any good offers on britax high back boosters, or maxi cosi high back boosters?
are the new style graco's any good?
