We are going to see family overseas and will be away for a month. We have a good travel cot, which our 11 month old sleeps in very well when we have been away before, but no more than 2 weeks. Should we look into getting a proper cot and proper supportive mattress considering we are away for a month, and the weather will be quite warm? Or would a travel cot be ok for a month? Baby sleeps on her tummy too... Advice on what people have done before!
