Definitely! The breast pump is a useful tool during the breastfeeding period. In the initial phase, the pump can help initiate or maintain breastfeeding, especially when your child is not yet used to latching on. This often happens under the guidance and advice of a professional, such as a lactation consultant or maternity nurse.
The pump can also be used during breastfeeding to build up a supply of expressed milk. This is useful for those times you are unable to physically feed, for example when you are back at work or temporarily need to supplement with expressed milk under the supervision of a professional.
