Apart from the chest-of-drawers style (which seem to cost hundreds), all the changing tables/cot top changers I've found state they are suitable up to 12 months. But potty training might not start until 2 years or older - am I missing something? What are you supposed to do between 12 months and, say, 2.5 years? (Just to clarify, I'm not looking for discussion on whether we need a changing table or when to potty train - I'm genuinely confused about what you're supposed to do after 12 months!). Thanks!
