@hayesmommy, yep. The boob is the best comfort. Some places even let you nurse during the vaccinations. You can ask or use a pacifier bottle or your finger for her to suck on during them. Good luck!
Well. If you breastfeed, nurse her right before and right after. White noise helps too. You can download an app for your phone or use YouTube. Favorite toy and keep her engaged with you during the shots. That's what we did with our son and he only cried for two seconds even though he had to get two extra pokes. Didn't need any Tylenol. A gentle thigh massage beforehand can help too
I usually wait it out, if shes really uncomfortable afterwards or starts to get a fever, then i give tylenol. But if this is her first round of shots you may feel better giving it before. Its a mommy choice :) what ever you think is better for him/her
