I don't normally post in here so forgive the intrusion
Just wanted to say something about the PCOS and BM thing. The research clearly shows that 33% of PCOS women will have an over supply of BM, 33% will be normal and the other 33% will not have enough of a supply or none at all. This is due to your hormones not being what they should have been during adolescence and therefore the right things arent in place now to BF. Usually a big indicator is how much your breasts grew during pg. If they didnt change size all that much it's almost guaranteed you will not be able to BF.
Also on the speech thing - follow your intuition. Also family history can play a roll (if there were late talkers in your family more likely your children will be late talkers). However stringing together 2 words by 2 is considered perfectly normal. My ds turned 2 middle of June and is not yet putting 2 words together but my DHs eldest sister didnt talk until 28mths - not a single word. There's a wonder week which ends around 2 and in the following weeks usually there is a huge word/speech explosion - this is when my ds has finally started coping all the animal noises and has started trying to say other words so I wouldnt be suprised if that's when Evie's speech takes off.
