When I was little my mum had a friend who was always like this. Her dd was perfect, and the mum always said "just do what we do, then your children will behave/do whatever." Then they had their second child. Totally different character, and it became clear that dd just happened to be a very passive, sweet girl. No.2 was the opposite - that shut them up!
That bf example is incredible. Apart from anything else (respect for the expressing - I managed 1 week, and that was too much!), I was so looking forward to breastfeeding cos I'd helped bottle feed dbruv, and found it so wonderful and intimate - I thought actually breastfeeding my own child would blow me away. Basically I never ever found any intimacy in breastfeeding - no eye contact, couldn't sit comfortably, could get both hands free so I could get on with what I wanted (writing, reading). I also couldn't cuddle ds when he wasn't feeing because of the pain. When I was bottle feeding we had the most gorgeous cuddles, full eye contact throughout, and because if I could only ever get one hand free (if I really put in the effort) he had my full attention. And dp could do all the same. So her assertion doesn't have to be true for everyone anyway!
