There are a number of key points during your pregnancy and beyond where you’ll consider if and why you might want to use a breast pump. It could be because you know that you’re baby is going to be born earlier than 40 weeks and you want to be able to express your milk if they need extra health support or it could be because you’re planning to go back to work and want to build a stash of milk in the freezer before you go. Whatever your reason, you’ll have a number of considerations to make as you navigate which breast pump might be best for you.
