Poor darling

OK from my personal experiences only

#1 - dummy around 6 weeks cos he wanted to suck but didnt want boob - I was petrified re the b/f - but it was great and he really settled with it
#2 - she had one from 2 weeks - b/f was established as far as I was concerned - no probs
#3 - introduced around 2 weeks again - but he fed like a pro too - AND he has only just had his last feed - nearly 15 months later!!!

So, at the age of your daughter - I would be confident that b/f is established. I must say I am shocked by the advice of the ABA re the milk drying up etc - if you are still demand feeding or every 3 hours roughly - I can think of no reason it would dry up. Please do not worry about this. She may still want to cluster feed late arvo - so maybe this is what the lady meant - so yes i would then give her boob over dummy for the time of day.

Types of dummy - my opinion is a dummy, is a dummy, is a dummy - i have used all the types and brands and dont think it matters - just dont start out at the top end of the market cos you will find it expensive in the long run

Re the length of feeds - my DD and DS2 only ever fed for 15-20 mins tops even as newborns - i was terribly worried with DD cos she chucked heaps too - but with DS2 - he got what he needed cos I had a very fast flow and lots of milk. So again, trust you and your baby first and foremost over advice that stipulates how long you should feed your baby first

I wish you luck - if it were me, I would try a dummy and see how you go hun xx
