Holidays, according to my pedi, were okay for the babies to attend as long as the youngest person was over the age of 18. The idea is that adults know how to sneeze and cough into their arms and wash their hands frequently and well.
My babies were born early in January. As soon as the weather got warmer, we were allowed to take them outside for as many walks as we wanted. Also, we were told that as soon as they had their first round of shots, we could take them into public places, but NOT drugstores. Drugstores have tons of pp who are sick getting prescriptions. So, I took Adam and Noah to Starbuck's a lot. I LOVED smelling their little heads after those trips...yummy coffee smell! :-)
