The 4-month sleep regression could potentially be causing nap problems. If your baby is sleeping less but crying more, try a naptime version of your bedtime routine, putting her down to nap when she begins to exhibit signs of weariness (droopy eyelids, yawning, wiping her eyes), and ensuring that most of her naps take place in her crib.

- Pumping. When pumping breast milk, you’re probably wondering how much breast milk you should provide for a 4-month-old. A baby needs about 25 ounces of breast milk a day. You’ll need to divide that by the number of feedings the baby typically has.

Make sure your baby is getting enough breast milk by checking their diapers. How many wet diapers for a four-month-old baby is healthy? About four or five very wet diapers a day.
