Dc #2 due in 6 weeks. Thought I had it sorted and had most new birn kit ready from dd and all left to do was buy new mattress for cot and moses basket but just read an interesting article that it all came about from a documentary in the 90s about chemicals in the mattresses which are no longer used. Now I'm confused. Obviously the safety of baby #2 is much more important than money but don't want to have to buy if I dont need to! help!!
