...just to let you know, Tesco are currently selling the Avent Isis breast pump (with 2 bottles and various extras) for £11.97 instead of £27! Absolute bargain
I know everyone's different but i started out with the Tommee Tippee pump and didn't get on with it at all (ripped my nips to shreds. Trust me, it only mimicks your baby's sucking action if you actually gave birth to a Dyson!), so i picked up the Avent one yesterday with my weekly shop totry, and it's fabulous. So much more comfortable. HTH.
