There will be so much going on at the 16th annual Oh Baby! Family Expo this weekend at the Blaisdell Exhibition Hall, you’ll probably find yourself saying, well, “Oh, baby!”

You’ll find three expos in one at the event, which also includes the Hawaii Toy & Game Expo and the Hawaii Party Expo. More than 150 vendors will be catering to the prenatal market and to families with keiki 10 and younger.

The expo is the “best place to purchase a baby shower, newborn or child’s gift; meet party vendors for your 1st birthday or upcoming holiday get-togethers; and play with STEM toys,” said show manager Anna Lau-Parish with Family Expositions.

There will be an infant and toddler play area, children’s activity area, and hourly performances and demonstrations on the main stage. Children can meet costumed princesses and superheroes. And back by popular demand, parents can remotely control a little Lamborghini, Mercedes or 4-wheel truck to transport their toddlers.

Also on the schedule is the popular baby crawling contest at 2 p.m. Saturday, and a group cake smash for toddlers 24-30 months old at 3 p.m. Sunday.
