Gabygirl - I reacted irritably because I posted to the OP, on my personal exp., then got each point patronisingly cut, pasted and annihilated by you. It really irritates me that I now feel forced to respond as it's a bit of a hijack of this lady's thread.
Your final post goes to illustrate my point that we did things slightly differently, and got similar results! Well fed, well slept, healthy kids.
Of course I b/fed on demand (9 times a day as it turned out god love him) to establish, but we then quickly fell in to a routine, mostly set by him, but recognised and stuck to by me. I obviously didn't stick a bottle in his mouth from day one. but within weeks yes, and he was adaptable as a result.
I had an extremely rough time of birth and post-natal and needed this routine, and then after an infection struck, the bottle feed from my partner so I could sleep and heal.
Not everyone can be on demand for their babies, same as not everyone can get to really good advice. When I did after the thrush struck, my B/F counsellor who is booked up for weeks and extremely well thought of in my area said that babies don't "forget" their original method of feeding, and actually encourage me to introduce another bottle feed to protect the feeding.
Her advice was fantastic for me and others I've spoken to and I just don't buy the nipple confusion thing for a baby who appears to be feeding normally after a few weeks.
But again, this is my experience, I'm entitled to it. Sorry to the to bogart the thread there. I hope you find the advice that works for you. Am off now
