Panna unfortunatley this will continue until 1)they can hold it in themselves by sucking and 2) when they can pop it in themselves. Millana my first had a dummy and i was continually getting up in the night for the dummy and not the bottle. Ruby doesnt have a dummy(she doesnt like it) so when shes older i want have to worry about it.Now she just cries more often and at times sucks her fingers. So you can percivere or ditch it!
They both have there advant/disadvant.
