Well, these parents obviously couldn't wait!
These babies have been dressed up in their dad suits, just to give us a brief - albeit hilarious! - glimpse of the future.
The new trend was started by Ilana Wiles, a mum of two from New York, when she posted a picture of her nephew Jack "wearing" his father's jacket, shirt and tie on her blog Mommy Shorts.
But it wasn't long until her picture was joined by many more other babies in suits!
The babies all look fairly happy now but we guess they'lll be another embarrassing photo to be brought out at their 21st birthdays!
