It is not uncommon for children to experience some discomfort or side effects after vaccinations, such as a low-grade fever or soreness at the injection site. However, it is also possible that your toddler is waking up at night due to other reasons, such as nightmares or a change in their sleep schedule. If your child’s sleep disturbances continue or if you notice any other concerning symptoms, it is always best to consult with your pediatrician.
