Congratulations on your little boy! So happy for both of you!
I am not a fan of vaccinations. There are too many stories of babies who were not the same after receiving their shots.
A site to hear some of those stories is http://www.vaxxed.com/home/
Two people here on Steemit that I would recommend are @canadiancoconut and @reddust. Ms coconut writes exclusively about vaccinations.
