Understanding what to expect and how to manage any reactions can help you feel more confident about your baby's immunizations.
This comprehensive guide will walk you through common side effects, management strategies, and important warning signs to watch for after your baby's 2-month vaccines. We'll also explain why following the recommended vaccine schedule is essential for your child's health.
