Babies should eat every 3-4 hours. Most babies like to take a walk or a ride. Try patting, rocking, singing, reading to them, or distracting them with toys. If active things do not work, try making things quieter. Maybe your baby needs to settle down to softer lights and music.
Babies like to feel warm and secure.
There is no right answer. What works today may not work tomorrow. Have someone else take care of your baby for a short period of time. Get advice from someone you trust. Sometimes talking to another person can be enough to help you.
