Need advice from parents of multiple children

I’m a stay at home mom to a 2.5 year old and a newborn. My husband is going back to work soon, and I literally have no clue wtf I’m going to do when he does. I currently spend most of my day on the couch nursing our newborn. My toddler, like most two year olds, has tons of energy and is pretty spicyband dealing with a little jealousy because of the baby. I’m planing on doing a lot of baby wearing but any advice at all from parents who have had to tackle solo parenting a newborn and a toddler would much appreciated bc I’m scared 😩
