When grandparents and grandchildren hang out on their own, who knows what they really get up to? If these images are anything to go by, then it’s crazy adventures.

Lots of grandparents spoil their grandchildren. It’s just the way it is! Unfortunately, grandparents often also teach their grandchildren things they shouldn’t yet know.

But David has apparently taken inappropriate babysitting to a whole new level.

David recently became a granddad, and he just couldn’t wait to do all the things that grandparents and grandchildren do together.

When he heard that his daughter and her husband were taking their first post-baby vacation, he leaped at the chance to look after his grandchild, Ty.

David was determined to spend the entire week with Ty doing fun and exciting things.

Some grandparents would consider the fact that Ty was only 8-months-old as a hitch to doing crazy activities. But not David, apparently.

On the day of the vacation, David flew out to meet his daughter, Stephanie, her husband and most importantly, Ty. Stephanie spent time trying to tell David how to look after Ty. But all that David would say was that he raised her fine, so he knew what to do.

So Stephanie and her husband left David and Ty, hoping that they wouldn’t get any worrying messages while they relaxed. They were wrong.

As soon as Stephanie and her husband had landed at their destination, they got a strange text from David:

Apparently, Ty had been having a whale of a time. Both Stephanie and her husband thought that the image was cute.

They then tried to relax and enjoy their vacation. But David wasn’t done yet.

Another image arrived from David. This time, the note in the picture announced that Ty had done a lot of growing up in just a few hours:

The parents then got back to their vacation. But there was still more to come. The next morning, when they woke up, they saw that they had had another message from David and Ty.

If the baby’s sheets are anything to go by, this message could have been genuine. The baby obviously loves cars!

But David’s images would only get more elaborate. He then sent Stephanie another picture of Ty, this time indirectly announcing that he couldn’t wait for a license or a vehicle of his own:

David realized that his daughter and her husband probably wanted to just get on with their vacation by now. So he decided to only send one more picture. And this one would be the most extreme of all.

Stephanie and her husband had loved receiving the pictures. But then she realized just how much effort her father had to put into them. David had no idea how to work the printer at her home. So he must have printed them off before he arrived to look after Ty. Just how long had he been planning these images?

No one can deny that the pictures of Ty and his adventures are hilarious. And it’s a really strange way for David to prove that he’s a great grandfather!
