breast feeding info . please help ❤️

Emma • First baby due 15th Feb 17 Baby BOY 💙
When my baby's here I want to breast feed for about 4 weeks. As I feel like I know I will be able to breastfeed him whenever he wants and I'm quite prepared to do the feeding day and night.
But since a lot of people say they pump and then store the milk has me thinking. Why have you chose to do that ? Do you need to ? Or do you want too ? Is it easier or harder ?
The same question to moms who give baby's milk all the time straight from the boob .
Any moms who store milk and any moms who don't have any words of wisdom about either way ??
