My wife and I just had our second child in late October. It's amazing the things you forget about infants between baby #1 and baby #2. Thankfully, there's videos like this one that are a nice reminder of what NOT to do.
If the video won't play - go here: https://youtu.be/sn4wp3pmu-8
Why don't they show these videos in the parenting classes? They would be very helpful.
