I am preg and not bfing atm but a friend of mine is and is stuggling to wean

Her son is about 15 mths and is almost using her as a dummy
He wont settle for anyone else if she is around and is very much a mummies boy (which is understandable) but its getting very hard on her to sit and feed for along time (she knows he's getting milk not just chewing) just to get him to sleep. Its hard and I think she is begining to resent it and we have talked of weaning and she really wants to she had had enough bfing
She has tried giving him milk in a bottle but he wont take it, tired putting him down awake not working, tried a dummy but not talking that either
So what I am after is any advice I can give her from u lovely ladies

Plz any advice is more then welcome she is willing to try anything
