Ask which 18 month pediatric vaccines are recommended today, whether any doses were already completed, and if catch-up timing applies.

A sore leg or arm, mild swelling, or tenderness at the injection site can happen after 18 month shots for toddlers and often improves within a day or two.
Some children are clingier, sleepier, or less interested in eating for a short time after vaccines. These short-lived changes are commonly discussed at vaccine visits.
If symptoms seem stronger than expected, last longer than your pediatrician advised, or you are unsure whether a reaction is normal, contact your child’s care team for guidance.
