On my experience, better go confinement center

Pros
1) more people take care of your wife & baby
2) fixed cost
3) insta worthy food pictures

If you taking confinement lady

Pros
1) stay home

Cons
1) 1 person settle all, she will be very tired and may not give your wife & baby 100% focus
2) variable cost, week week will ask buy this buy that ..
3) if the lady is a creature of habit, then your wife will everyday eat same kind of food until she jelak
4) your house will be dirty unless you got maid or yourself clean the house cos confinement lady wont clean

it is also a gamble sometimes with confinement lady, sometime you get good ones , something nightmare ..

pricing wise, confinement center 10-15k like you said but its all inclusive
confinement lady last year i hire was 6.8k and havent add all the food / herbs / what ever other shit she ask ... it was a nightmare for me, i asked her to leave after 4 days.
