Toddler acting out after we brought our new baby home

Our two year old son has always been so sweet with tons of energy and occasionally acted out. But overall a really good child.

However we brought our new baby home a couple weeks ago and our toddler is completely out of control. Spitting, stripping his diaper, peeing on the floor, going absolutely wild before bed, biting my husband. The only person hes been kind to is the baby (all he wants to do is kiss his brother and be sweet to him).

Has anyone else gone through this with their toddler acting out? Hes turned into a completely different person and on top of sleep deprivation from the newborn, we are just exhausted from it all.

Any suggestions on helping him deal with the nre life changes so he can get back to his normal sweet self are appreciated.
