Hi everyone I was in here a couple of months ago asking questions and had lots of wonderful advice from you ladies. I am hoping I can pick your brains again please, I realise this is an exclusive expressing thread and while I am not exclusively expressing, I figure you would be the best people to ask for expressing advice! I have been using my pump since we got home from hospital, I have an electric Tommy Tippee which I have found great. Unfortunately I got mastitis in week 3.........partly from oversupply and partly from me thinking it was a good idea to go back to work super early as I thought I was wonderwoman (which I am not!) So I gave up on the pump for a while while I recovered from that. I have started pumping again in the last week. I am working half days at the office and expressing 1 - 2 times during this time.

X is 5 weeks old and I am building up to more time in the office and will be pretty much doing full days in a month or so. This means I really need to get this whole expressing thing sorted. So I am wondering:

1. Is it right just to express the breast that X would normally feed from at that time? I am doing one sided bf as I have big supply
2. For those that steralise, do I need to be steralising the pump again between expresses (I am at the moment) or can I put the pump in the fridge and this will keep it sterile? It doesn't sound right to me but I read it somewhere........
3. I am getting 150 mls from one breast easily in about 10 minutes but only about 100 mls from the other one in about 20 mins, is this unusual?
4. How long does expressing take you and will it get faster? I am happy with 10 mins but 20 mins feels like forever when I am at the office.

Thanks everyone in advance
