I've been worrying myself sick his entire life. he's hat 2 dtap and 1 hib, i'd like to get 1 more dtap and mmr and varicella. I'd like to just do all three at once instead of prolonging my worry of both getting the vaccine and getting the disease! chicken pox isnt too scary but i've had mother friends not vaccinate against it and say they wish they had gone ahead. is it too much to do those three together?
