The fact that so many are admitting to being spectacularly poor parents is astounding. There is no good reason the kid couldnt sit still and even less reason for a 25yo to attack it.
We have always taken ours everywhere including really uoscale restaurants...and weve had to pack up and leave a couple hundred dollars worth of food on the table if the situation couldnt be managed within one or two minutes
That only occurred a couple times and people always tended to be shocked at how well mannered even 2 year olds can be wtith the proper attention and guidance..granted they have mom 24x7 and dad every non working waking hour interacting
