@abby.r1554, lol I've heard of stories like that. I will definitely watch out

He once walked up to the baby in his bouncer and slapped him on the head while we were standing right there.

My aunt's babies are about a year apart and her best advice is to take it one day at a time and try to keep an eye on the one year old. Hers is 1.5 years now and her baby is almost 5 months and the 1.5 yr old will intentionally hurt the baby when people aren't looking... In the car you have to tell him to be nice to the baby every few minutes or he'll start pulling the baby's leg and pinching his foot.
