I am returning to work in two days, my 7 week old is EBF and will be getting about 3 bottles of breastmilk a day while I'm at work. I plan to pump every 3-4 hours, my question is storing it while I'm at work. Can I pump into the same bottles all day, just keep adding to that? Can I add fresh milk to already cooled (not frozen) milk? How long can my breast milk be out at room temp before it needs to go into the fridge/freezer?
Also, my son has started sleeping 6 hour stretches at night. Will this affect my supply? When I do feed him in the middle of the night around 1-2 am he seems like he is getting enough and I am not feeling too engorged. I just really want to breast feed until 9/10 months and I don't want my supply to be affected. I'm also worried that pumping at work is going to slow my supply down. I am also terrified he will reject the breast, he has only had a bottle 3 times since birth. I will be feeding him at 6/630 am before I leave, and then again at 5 and before bed at 8/8:30. I work 9 hours only 4 days a week - please help! Can someone reassure me my breastfeeding relationship with my sweet baby wont be compromised? Thanks
