Hi everyone, I'm new here & this is my first post, but i've found loads of really helpful advice on this site for a first time pregnancy! I'm 30 weeks pregnant so trying to get the nursery sorted, and bought a Mamas & Papas Rosalia cot off ebay last week (am obviously buying brand new mattress!)DH assembled it this weekend and have just discovered that it only has one level for the mattress (lowest level). It is a dropside cot, but i am now worried that I may regret this purchase due to it not having an adjustable mattress height. How important is it to be able to change the height? Should it sell it on and get another one? Help!!
