The same thing happened to me when i moved up to the L domes.You can use as Anastasia said some extra lotion/cream and another suggestion would be to put the domes one at a time.Put the first one on your breast,hold the tube of the other dome so it won't leak air when you pump,them pump the first breats,after getting a good seal,hold the tube of that dome that you pumped then put the other dome on the other breast and pump,when you get a good seal you can leave the tube you were holding .That was the only way i was able to pump for the first couple of weeks.Good luck.
