I am a mother of 4 children. I have had my last 2 here. When my third was a baby I took him out when he was about 2 weeks old to the City Centre. I was followed by a woman tutting and muttering in to the toilets where she chastised me for bringing such a young baby out etc etc.
I don't know why, but I defended my self to her ... and afterwards I too cried (it's those blinking hormones).
Some of the advise we get given here is incredible ... I was also once told to give my baby iron as she was too white (this was at 4 months of age and both myself and husband are white skinned people)
I have learnt to smile now ... people mean well, it's not done maliciously. It's just that we don't do this in our own country as it's rude (unless you're a motherinlaw!)
This is all part of the experience of living in another country and experiencing different cultures and ways.
I do feel for the first time mums though who experience something like this. But try and remember they mean well.
