I was a stay-at-home father for my daughter's first year - more out of necessity than choice, since as a freelancer I had no projects during the economic crisis.
Apart from a lack of intellectual stimulation, I attended several (mostly Expat) mum's groups and invariably was the only guy there (above two years old, that is). Having little to add to conversations about hair styles, maids and
condo search, I focussed on the little fellows.
Our daughter also attended a rock concert at two weeks old, visited Orchard Road soon after, Bukit Timah hill at two months and travelled overseas at four months, all carried on my belly.
Another (Singaporean) stay-at-home father I know constantly stayed at home, but I would have been bored out of my senses that way!
