Welcome to YT! In my experience my 3 are great with small kids. Like you my kids are all grown (my daughter is 15 and my baby) but our neighbors both have small kids all under 4 yrs old. You just need to keep a close eye for they don't try to pick them up. Injuries are very real and could happen easily. If you have grandkids and socialize a puppy properly I don't think there would be a problem. It nice to hear that you are thinking ahead and doing research. By doing so you will be very prepared and know how to address any issues that might arise.
