Hi, would just like a bit of advice. I currently use mainly TOTS cotton rainbows on my 20 month old. However,they are starting to get a bit tight. I am wondring if anyone can give me a bit of advice as to what to use on him. SHould I buy tots bamboozle in a size 3 or would an MEO see him through the next 6 months or so(I have about 4 of these and they do fit well for now)? I don't want to spend a fortune on more nappies and thought about picking up some second hand MEO's - this is only worthwhile if they would last him for a whil- perhaps to 3?? Any advice greatly appreciated!!
