According to me i think its more than enough but it also depends on your expenses!!! any how i think it is enough.
and if your wife is pregnent its very nice facility in qatar ,if u have a health card then delivery is free only you have to pay the bed charges.and bed chrges will be qr 100 per day thats it.

if you have permenent vis for yor wife her delivery will be free.........but dont forget to make her health card ok.
