My twins will be 16 months in october when our new baby is due...obviously for first few weeks sling + double pushchair.And also there will be lots of help initially so can split them up BUT there will be times when we want to transport all 3 together, so what's worked for other MNers ? Does anyone know if you can still get a trad silver cross twin pram ? And what about those seats you put on top of them ? We have a while I know but my nanny and I were discussing it last night....she is not ' big ' on slings you see !
