DTS are now 2.10yrs, and are still in size 12-18 month trousers and skirts, I have all these lovely new clothes for them (size 18-24 months)and I want to buy them more but refuse to buy more 12-18 months as they are slightly too short but perfect round the waist, the next size up just falls down, and thats with a nappy on. Anyone else have this problem ans how do you get around it? the clothes they have are elastricated.
