Smash cakes have become very popular in the last 10 years so don't beat yourself up if you never did one for your older kids.
A smash cake is typically a small cake for a smaller child - generally a one year old but you could get creative and use it for any age. Even 50 year olds deserve smash cakes!
Be prepared - Put a disposable table cloth on the floor and, after the cute photos are finished, strip down the baby to the diaper or expect to have very stained clothing!
Have your camera ready! You won't want to miss this memory!
