The FSID recommendation is 'ideally you should buy a new mattress for each new baby' - but how many of you did buy a new mattress?
We bought a good quality mattress for DD, she slept in the cot for less than 2 years so it is in good condition - clean, no obvious wear and tear. And as we've had it from new we know where its been and what it's been through
What is the risk if we re-use, as long as we are careful about bedding, room temperature etc?
