I'd like to start pumping so my dh can share in the fun of feeding my 8-wk-old. I bought a hand pump, some storage bags, and I'm ordering bottles today. My dh thinks we'll need a bottle warmer and a sterilizer. I think we can warm the milk on the stove and just boil the nipples for sterility. Who is right? Since he will be doing the feeding, I am leaning towards just getting him these things, but I'd hate to throw out money if they're not necessary.
