Second baby guilt?

Ash • Wife 💙 Mommy to a little boy as of 3/17! 😍

I’m sure it’s been brought up before, but do any of you mommies out there recall experiencing mom guilt when you found out you were expecting for the second time? I’m confident I’m pregnant again but still too early to test. My anxiety has been through the roof thinking I can no longer use all my time for my son, who will be 2 in March. He would be the best big brother but I can’t help but feeling so jealous for him. Am I nuts!?
