I have a 4 year old boy diagnosed 6 months ago- joints affected left knee and both ankles. after 6 months of steroids and a corticosteroid injection to the knee, he started on methotrexate about 8 weeks ago. we are told it could take up to 6 months before meds make him pain free but for now, his knee (infact entire leg) is very swollen and he cant walk very far at all. we have a 16month old daughter and have a pram which when we are out for walks our son ends up int he pram or being carried. Problem is he is 25kg (side effect of steroid use is some weight gain) and most prams are up to 20kg. We feel we need to use one for him if we go even for a short walk as he is in so much pain after a short time it becomes very limiting. we would prefer he can hop in and out of buggy if and when he needs to rather than curtail walks and trips out altogether. We are going on holiday end of feb and wanted to invest in a double buggy that would take a child up to age 5- any recommendations or suggestions of how anyone else has coped?
