Can a four-month-old baby take it out to play?

Yes, it depends on how far and how long you walk, and some factors should be considered, such as changing the clothes your baby eats, mainly drinking milk at present, having water in the milk washing facilities, paying attention to your baby's emotional rest time, not making too much noise, affecting your baby's work and rest, and ensuring adequate sleep. At present, this factor should also be considered during the COVID-19 epidemic.
