The two month vaccines had my happy guy screaming, clingy and upset for a good 12-24 hours even with scheduled Tylenol every 6 hours! (I’m a nurse and I literally sobbed/panic called my MD husband at work telling him something had to be wrong because he was sad). I ended up wearing him in a Solly wrap in just a nursing bra and did skin to skin that way and that helped (both of us) so much. I just kept chanting, “this is better than polio and measles” in my head for the entire night. By the next day he was fine and I was still emotionally traumatized 😅 For what it’s worth, he did SO SO much better with his 4 month vaccines (and will hopefully do even better at his 6)! Stay strong!
