My son was born at 36 weeks Gestation. He was immediately taken to the NICU upon birth and spent 10 long days there. I of course wanted to breast feed just as I had with my 2 year old daughter. I was given a hospital pump to use while in the hospital which worked wonders but I could not take this home. A lactation consultant visited me before I had to leave the hospital because she knew I would be leaving my baby behind. She recommended that I buy either the Medela Pump In Style or the Hollister Purely Yours Pump. Well after much debate I went with the Hollister simply because it was smaller and looked much nicer and easier to use. Well I used this pump for 5 days straight pumping every 2 hours. This was the best experience that I have ever had with a pump and with my daughter I had tried many. The pump was VERY light weight the breast shields were easy to use, they seemed to fit perfectly to my breast and I never had a problem with the suction being accurate. There was a dial for the suction and the speed in which the breast was pumped. I loved this pump so much. It was a true life saver to me while my son was in the hospital. I used this pump at various times while I nursed my son and it to this day is still an excellent pump that will last many years longer I am sure. The bottles were a great help as I had to take them to the hospital for my son and this pump came with 4 bottles with extra rings. It also came w/ 2 ice packs which were another GREAT help to keep the milk cold on our way to the hospital. I am very thankful in my decision to purchase the Hollister Purely Yours Pump. I wouldn't have it any other way!
