Allow me to tell you this. The fuc**iest thing you can do at my house, is to put my 5 year old cousin with both my grandparents. My cousin can probably die of crying and choke on his tears because my grandparents know balls about computer, internet, miniclip.com and Club Penguin game. And my grandma likes to irritate my cousin when so obvious the child isn't paying attention at all.
And one thing I learnt, never leave your child under the care of your sister or brother. Your siblings' family environment may not be the best place for your child to grow up. I'd say, my 5yo cousin's future life is half-ruined by just staying at Daniel's house.
In fact, i think my aunt herself can really nurture his son very well and may be even better than how my mum brought me up( she just chucked me and my 2 elder sisters to my grandma while she hangs outside and enjoy life when she was 30+ then).
Fuc* it man. If you're not going to do your best to take care of your own child, who's going to do that? Except perhaps your spouse.
And uh, my 5yo cousin surfs the internet. GeezZ ! I only started using the computer frequently when I was primary 6. Computers totally transform adolescents' life nowadays.
