Anxiety on High— am I overreacting? FTM problems...

Back story... I have had 2 miscarriages before my beautiful and perfect baby boy came into this world 3 weeks ago. So needless to say... everything has my anxiety on high since I found out I was pregnant.

Fast forward to about 40 minutes ago... I was starving cause I hadn’t eaten all day and I knew he was coming to the end of his nap... so I made a Pb&J. Got peanut butter on my thumbed and I licked it off. LO started to wake up so I quickly put hand sanitizer on and waited for him to wake up.. so I touched my PB&J again to take a bite... well about that time he woke so I grabbed him and pulled out the boob and used the same hand I got PB on and touched my sandwich to make a boobie sandwich for him to latch. Now I’m scared he ingested peanut oils and could have a reaction. So far no swelling, redness, hives or labored breathing. How long should I keep a super close eye on him? Do I need to do anything else? Or am I being dramatic like my husband and mom insist I am being?
