I am due in a few weeks and ds will be two about then as well. He is well off bottles now but I have kept them all as you do along with all the different teat sizes etc. Should I throw everything out and start again for dd or can I get away with using things again. Just worried that plastic etc might have aged although it does all look ok. Am planning to breast feed for the first six months with just the nighttime bottle but want to have planned for everything!
