I have been back home a couple of weeks ago and what is expected has happened: lots of remarks on the necessity of me weaning my 15 month-old. My MIL told me a story about an ignorant woman who was (disgustingly!) nursing her 4 year-old in order to not get pregnant. My father said I should wean by 18 months at most because he will be too big to nurse after that. A family friend who is a psychiatrist said nursing too long will cause psychiatric problems as an adult. Her husband, who is also a doctor, said there is no research that indicates that there is any benefit of BM after 1 year and that I should give my son Similac Advanced2 . Apparently, my boobs are everybody's business but mine I was also told by a colleague that I should wean because 15 months is enough. Here is my question: Since I have never asked anybody when I should wean my son, why does everyone feel the need to order me around on this issue? I don't take any of this unwelcome advice seriously of course but still it is disturbing to have to defend myself on an issue that is nobody's business.
