樓下的留言are very useful, I have all mentioned experience. My bb 埋身餵 1st month, pump 2nd month coz nipple bleed and painful. Since I fire my maid 3rd month I 埋身餵 again, BB can suck very good la. Now my BB is 4 month old she is half 埋身餵 and half bottle餵 ( To know how much BB drink). So far so good, she is heavy and healthy and happy!
PS. Avent hand pump quite comfortable.
Electirc pump little painful at begining, but you get used to it later.
