So guys I pumped last night for about 15 minutes and was able to fill the bottom rim of the bottle! I have pumped twice today, due to pump again in an hour and a half. I do have a double pump that is not hospital grade *i don't think* Its the first years double pump, anyway it worked great before I stopped nursing and it seems to be doing the job now. My only problem is my 3 year old son lost one of the valves so I can only pump one side at a time until I can locate it. I'm so glad I decided to do this but I wonder how long it will take for my milk to come back up.
