Yes, restaurants will give birthday desserts to 18 month olds.

Buddy's 18 month birthday is tomorrow. I can't believe it! It came so fast!

So today, my parents, buddy and I went to lunch. during lunch, I somewhat jokingly suggested we let them know it's buddy's birthday and see if they'd bring a birthday dessert.  

So, we told our waitress we were celebrating a birthday and let her know it was for the baby.         Um, do you bring desserts for18 month old birthdays? we asked.  Sure, replied our lovely waitress.

So, a birthday sundae was brought out for buddy to enjoy. Complete with candle and all. He was so excited.  And he definitely enjoyed that sundae. See photos below.

So, two things - one, happy 18 month birthday to my precious, happy, sweet little boy. and two,
whether you're 18 months or 18 years, everyone loves a restaurant birthday celebratory treat!
