Hi, a few recommendations please! I have an 18 month old and a 28 month old that are both big for their age - my 18 month old is easily taller than most 2yr olds and my son is only 2 but is comfortable in age 4 clothing. Because of ages, both still need a little stroller for when they get tired, but most won't take my son's weight (he's nearly 16kg. Like I said a strapping boy!). Does anyone know of any? I had the Britax double which was fabulous, but just too bulky.
