Read up on sibling rivalry/jealousy. Just as if you had had a baby and brought them home your older child is now having to share you, their house, their toys etc. with the baby, deal with the baby's noise when they cry etc. Rather than time outs bring your child into helping you care for the baby so yes the baby needs to be the centre of attention at first but together you and your child care for the baby such as holding the diaper for you while you change instead of getting into trouble while you are busy.

Family daycare is just that - a group of children and a daycare provider that for working hours pretend to be a mom and a group of siblings with all that that entails. Some days go better than others for sure.
