My baby is five weeks old. She was born naturally, at 40w+3d in a pool, I was in hospital MLU for grand total of 10 hours ( I really wanted to get home to my own bed) and was perfect on arrival - no complications, no drugs for either of us etc. A textbook delivery in other words.
I didn't buy a pump in advance, having read the stuff that says do not introduce bottles too soon etc. Unfortunately, baby lost 10% of birth weight in first week - thats a bit too much. She seemed fine in herself no jaundice or anything but because she was off the graph I was on special measures i.e. a visit every 48 hours to weigh the baby.
Because it was Christmas I had a random selection of midwifes, community assistants, lactation consultants visiting - I suspect if it hadn't have been Christmas then I might have had the same person more consistently! Anyway, one of the visitors, I think the LC (the early days are a bit of a blur), said I needed to express after every feed to get my supply up and give it to the baby by bottle last thing at night. She also very helpfully lent me a pump - Medela Swing - and a sterile baggie of 'disposable' bits i.e. funnel thing that goes on your boob, silicon air tube, bottle and teat. She also told me to look on ebay for a pump and save a fortune. Finally, she said avoid Tommee Tippee but I can't remember why! It was either comfort, speed, efficiency or noise.. she said they always lend out pumps to women for 48 hours, but as it was Christmas and she was off for 11 days I could keep it until she got back
Baby is now fine on both bottle and boob - I was really paranoid about 'nipple confusion' so sent DH to Mothercare to buy an eye-wateringly expensive Medela Calma teat which allegedly works more like a boob. This made me feel better about it, and I think may have actually helped baby 'learn' to do longer harder sucks. I could be delusional on this point though...
Anyway by week 4 she was back up to birth weight. I got the pump (Swing) off ebay, and as I already had the sterile bits I felt ok about second hand. It cost me £35 instead of £130 in Mothercare (or £90 on Amazon).
I subsequently read a thread on here about open and closed pumps though so maybe run a search and make your own mind up? It basically says the Swing is an open pump so milk can get into it (unlikely but possible) and so not a good idea to use second hand - but as the NHS lady lent me one (and I had already bought one) I kind of ignored this?mine looks clean and baby seems fine!
Anyway, my suggestion is speak to your midwife/local MLU or wherever you are having the baby, see if they lend anything in case of need/emergency and if so what - I gather our NHS (South Wales) uses Medela, so made sense to me to trust them and get that.
Apologies for long post!
