2 to 3 months.
The Correct Answer is D
The correct answer is D. 2 to 3 months.
Choice A rationale:
The posterior fontanelle does not close within 3 to 6 months of birth. This timeframe is too long for the typical closure of the posterior fontanelle.

Similarly, the posterior fontanelle does not close within 6 to 9 months of birth. This period is beyond the usual closure time for the posterior fontanelle.

The posterior fontanelle does not close within 9 to 12 months of birth. This timeframe is significantly longer than the typical closure period for the posterior fontanelle.

Correct Answer is ["A","D"]
Explanation
Choice A rationale:
Offering foods that are varied and colorful is a good approach to support a toddler's desire to self-feed. Colorful foods are visually appealing to children and can encourage their interest in trying new foods. A variety of foods also provides a balanced diet.
Choice B rationale:
Foods in colorful dishes are not directly related to supporting a toddler's self-feeding. While colorful dishes can make mealtimes more appealing, the focus should be on the variety and type of foods being offered.
Choice C rationale:
Pureed foods are not typically offered to support a toddler's self-feeding. Toddlers are generally transitioning to solid foods and finger foods to develop their motor skills. Pureed foods are more suitable for infants.
Choice D rationale:
Offering finger foods is an appropriate choice for supporting a toddler's self-feeding. Finger foods allow toddlers to practice their fine motor skills and become more independent in feeding themselves. It's a crucial developmental milestone for them.
Correct Answer is A
Explanation
Choice A rationale:
Push-pull toys are suitable for a 3-year-old because they promote physical activity and coordination. These toys help children develop their motor skills and provide a fun way for them to engage with their environment. Push-pull toys are age-appropriate and safe for toddlers.
Choice B rationale:
A large construction set may have small parts that could be a choking hazard for a 3-year-old. It's essential to select toys that do not pose such risks and are developmentally appropriate. Therefore, this choice is not the most appropriate toy for a 3-year-old.
Choice C rationale:
A small pet, such as a goldfish, is not an appropriate toy for a 3-year-old. Pets are living creatures that require care and attention. Introducing a pet to a young child should be a well-considered decision made by the family and not seen as a toy choice.
Choice D rationale:
A board game is typically too complex for a 3-year-old to fully enjoy and understand. Board games often require following rules, taking turns, and using fine motor skills that may not be well-developed in a child of this age. Therefore, it is not the most appropriate choice.
