Dealing with Older Sibling

ᎢᎪᏚᎻ
I am 2 weeks PP. Since I've been home, my 5 year old has been driving me crazy! This is his first sibling and his excitement is through the roof. He seems to be going a million miles per hour. I am trying my best to be patient with him, but I find myself constantly upset with him for being "too wild", touching baby too much, being too loud, etc. I feel so guilty and even more so considering I am unable to spend time with him like I have for the past 5 years. I'm worried he will feel I don't love him as much. 
Any advice on how to balance things? I don't want my first precious little boy to ever feel less than 😔
