What is normal behavior after baby's 6-week vaccination?

It is common for babies to be extra sleepy, cranky, or experience a temporary dip in appetite following their 6-week vaccinations. This discomfort usually lasts for about 2 to 3 days. If the rotavirus vaccine was included, some mild vomiting can also occur. If you are concerned about your baby’s hydration or pain levels, always consult your pediatrician, who may suggest infant-safe pain relief if your baby is refusing to feed.
