My DD is 6 months now and I'm due to go back to work when she is 9 months. I need to leave expressed milk for her but won't be able to express at work. So I thought of starting now to build up a supply and freeze it. But I have no idea when to do it. She feeds every hour during the day when we are at home and 2-3 hourly at night. How long do I need to wait after feeding her? Could I put her to bed and then pump after 1 hour? How long does it take to express? I've got a manual Tommee Tippee one, only used it once when baby was a few days old as the midwife said I needed to know how much milk she was getting. Was awful, hardly drained anything. Also do I need to sterilize everything if it's expressed milk?
TIA
