Great advice! Thank you Karren. Since you're so nice, could you also kindly let me know what the difference is between the regular cups and the contoured ones? I'm not sure which I should get. I contacted the store but got no reply......also are the airlocked noogleberry cups contoured or regular?? I think I should get the airlocked ones so that I don't have to hold the hand pump the entire time (if I understood correctly...). 
Thank you!
