Children always cause trouble, have difficulty sleeping, what should I do?

Patient's question:

Detailed medical condition and consultation purpose: My child has been constantly fussy lately, and it's very difficult for them to sleep. Could you please explain what might be causing this? Additionally, could you please ask the expert what the normal body temperature should be for an infant of this age? Thank you

Doctor's answer:

Babies need good sleep for healthy growth. When a baby's sleep is not good, how can we help the baby have good sleep? This requires a caring mother to create it for the child. First, create a good sleep environment for the baby. It is important to know that a baby's tactile sensitivity is relatively high, and even slight movements can wake the baby. Therefore, when the baby is sleeping, parents must ensure that the environment around the baby is quiet.
