After the baby has been injected with various injections, it is important to observe the injection site for redness, swelling and pain, and if there is no localized inflammation you can take a bath on the same day. If there is redness, swelling or pain, it is best to wait until the local symptoms are completely eliminated before bathing to avoid aggravating the infection at the site of the needle. You should also pay attention to measure your baby’s body temperature, because many children are likely to have a fever after receiving certain vaccines, so you can choose whether to take a bath or not based on the temperature in a timely manner. If the fever is present, bathing is not allowed. If the temperature is normal and does not recur, bathing can be considered. If the baby is non-verbal and cries continuously after the vaccination, it may be due to physical discomfort, so do not bathe the child immediately to avoid the child being frightened and the crying worsens.
