I am expecting my third in March. I already have 2 year old twins who can walk quite nicely when they want to but we will still need a pushchair for them. Any suggestions on a double buggy with attachment for a baby? From googling, none of the pram makers seem to have thought that anyone would have twins then a third (there are plenty of options for single toddler plus baby twins but not the other way round)! I am planning on carrying the baby in a sling a lot of the time but if anyone has any suggestions on pram/pushchair solutions for toddler twins plus baby, I'd be very grateful!
