Breastfeeding.

Hi mummies.. I've just given birth three days ago on Mothers day. Baby is day two now. I have a question. I decided to direct latch feed on demand for my baby however baby is demanding for milk every hour which makes my MIL and confinement nanny and my hubby thinks I don't have enough milk to satisfy baby and insist I pump out and bottle feed my baby. Baby was fine from breastfeeding in the hospital latching an hour (30 mins each side) and self detach latch after satisfied and comes back for milk after every three hours. But after reaching home baby starts to cry for milk every 2hrs then 1hr. What should I do?
