Final answer:
To gain baby Ricky's interest and keep him focused during a photo session, it would be best to use colorful and noisy toys to grab his attention. Allowing him to explore the photography equipment, keeping the environment quiet, or offering snacks may not be as effective.
Step-by-step explanation:
To gain baby Ricky's interest and keep him focused during a photo session, it would be best to use colorful and noisy toys to grab his attention. Infants are attracted to objects with sharp contrasting colors, complex patterns, and anything that is shiny. These types of toys can help keep him engaged and focused on the photographer.
Allowing him to explore the photography equipment might not be the best option as it can be dangerous for the baby and may lead to distractions. Keeping the environment quiet can help avoid distractions, but it may not be enough to maintain baby Ricky's focus. Offering a variety of snacks may also be a distraction, as the focus would shift from the photographer to the food.
