When i gave birth to my 1st one, I too thought that breastpump is not necessary, until I experienced engorgement during after 2nd day of birth. It was so bad and the milk was leaking non-stop whilst baby couldnt drink that much. Hubby decided to go to the shop below (i was at Kandang Kerbau Hospital then) to get a breastpump and store my milk in the plastics to freeze them. After pumping it, Felt so much reliefed!!! (Can cause you to have slight fever if the engorgement remain)..
Anyway, We bought Avent manual pump, and I must say that it works wonders! At the same time, I tried Medela Electric Pump on loan by Kandang Kerbau Hospital and I must admit it was pretty hassle-free having electric ones around. But if you are on a tight budget, trust me, Avent works wonder and I could get a 90ml Milk within minutes..
