Dd2 has ASD, we have been looking at getting a special needs 3 wheel buggy but they are very pricey, we just want something that we can use when we go walking or to car boot sales and thought a bike trailer that can be used as a buggy would be good. Trouble is I cant find what age they go up to, dd2 is 7 (thin but tall), would she be ok in a 2 seat bike trailer? can anyone recommend one that's sturdy??
