Zack is 5 mos (corrected to 3 mos). He is doing great. He is happy, healthy and 13lbs already! He just had his routine immunization shots. He was screaming for about 10 minutes afterwards and it left him a bit cranky and fussy for that night and the following day (which is not like him at all). I just got called that he has been schedule for his 1st synagis shot Nov 20th. I hate the thought of giving him more needles. Has anyone experienced any bad side effects with this drug? Has anyone debating whether or not to actually get this done? Everywhere I have looked on the net it is just assumed preemies get this shot. Anyone else feeling unsure about it like I am?
