my boy was happily sleeping in a single bed at 15months (we had one though so it wasn't an additional expense). Will bubs be in a bassinette?? if so remember you have an extra couple of months to make the transition.

Some form of double pram (whether toddler seat or what) probably won't hurt - I always swore that my toddler would walk once he could walk properly but there are times its just toooo slow or unsafe so even now (and he's about to turn 3) I bought a double pram (off ebay) just before Samuel was born so I could go for walks, busy shopping centres etc with both of them on my own. There are also the stands that clip onto prams but they aren't cheap either (but I'd be looking on ebay for anything). Maybe a baby carrier (if you own or could borrow) would benefit while bubs is tiny and you could then have time to decide once they are both around and you know what level Tayneesha is at.
