And if you have either of these in your life... you'll know how impossible that piece of advice is to follow!
I have one of each; 1 Toddler, 1 Labrador. They're a mischievous duo at the best of times, but with my 'baby business' too, it's fair to say 'never work with Children or Animals' is definitely not a rule I stick to.
Instead, I accept there will always be a strong probability of chaos.
And it meant that when I recently held the first Pretty Little Polka Dot photo shoot, I was ready for mayhem.
So, armed with a selection of our most popular handmade creations, and with a very special group of little 'Polka Tot' models in tow, we all descended on, what was once, a quiet and peaceful park in Devon.
Sunshine and Blue Skies
The weather was glorious (yes, it was that day)! Our little models did a fantastic job being cute, and in most cases managed to look in the right direction too!
Snapping away, we managed to get lots of beautiful shots - The final photos are now up on our home page. But be warned, they're seriously adorable!
I am so grateful to the Mummies and Daddies who lent their little 'Polka Tots' to the cause, and to Hannah also for the photography.
Here's a little selection of the photos from our day. A day which I am pleased to say, despite my expectations, didn't descend into chaos!
