I'm just wondering what most people do.
DS2 is 5 months old, and spends his nights in my bed (wouldn't settle anywhere else). I'm going to try and move him into a cot but I'm not sure if it's OK to use DS1's old mattress because of SIDS risk.
The old mattress has a plastic fixed outer, and a removable washable cover. I assumed that would mean that no nasty bugs etc would be able to permeate it. And the cover can be washed at 60 degrees.
What would you do? Buy new? Os use old?
