If super basic need like you mention, 5k is a good amount to start. Excluding baby gears.
I think the budget should dictate the items and not the other way around. :-)
Naka 15K nako, pero wala pa crib, pillows & blanket, nursery bag, & stroller
Ang sa Akin 12-15k.. Not included the stroller, crib, carrier
depende if san mo plano bumili sis :)
