Nope, it won't make a difference If it makes you feel any better, as you have probably read my threads, we've been going thru the same thing... frequent night wakings, and still feeding sometimes 2-3 times a night here and DD turns 1 next week!
However in saying that, the last week she has been MUCH better! not sure whether it's to do with the Osteopath we took her to see and/or the Brauers Sleep Relief spray we bought and give to her before night.

i know it's hard. I know how tiring it is.... we will all get there in the end.

You're doing a great job BF'ing and your little girl doesn't need any FF.
BTW, we have tried that, and it didn't work....(AND it made me feel like cr@p but i was desperate that night ) and we have tried filling her up more for her evening meals, pasta etc but nope that doesn't work either

She'll sleep through when she's developmentally ready to.
