To cut a long story short, from the start my son had latch issues related to tongue tie, a slightly recessed jaw, and tightness due to a forceps delivery. I won't go into detail but here are the previous threads if anyone is interested:
I rented a hospital grade pump (Ameda Elite) when he was around 6 weeks old and have been using it for 2 months. His latch still isn't great but it is slowly getting better, and I am no longer in pain, although he does still sometimes chomp on my nipple and I have to position him carefully each time. He feeds better some times than others, sometimes he softens my breast well but not always. He usually seems satisfied after a feed, although he doesn't get 'milk drunk' like he did at the beginning - he either falls asleep, or he wants to play. I feed on demand and offer regularly, even if he isn't obviously asking - he will usually have some.
His diaper output is ok - plenty of wets and at least one big poop a day, although sometimes he will also do smaller greenish poops. He has always been a fairly slow gainer and is gradually dropping percentiles very slowly (I think something like from the 7th to the 2nd), but always gaining and roughly following a curve. He is growing in length, meeting all milestones, sleeping well, and is generally a happy, active and alert baby.
We have been seeing an osteopath for the past 6 weeks or so, I'm not sure how much it is helping or whether things would have improved anyway. The very experienced IBCLC we are also seeing thinks it is helping, she is also generally happy with how my son is progressing and feeding, but said to make sure I feed him more if his poops are green.
I am only pumping once a day now, and my husband feeds him milk expressed the day before. I always manage to pump what he drinks (around 100 ml), sometimes a bit extra, which I then freeze.
I am wondering whether it is ok to return the Elite and use the Purely Yours instead, which I own. I have spent a LOT of money on breastfeeding (books, pump, seeing the IBCLC and osteopath) so could do with saving the cost of the rental - on the other hand, I don't want my supply to drop. I am still taking fenugreek 3 times a day.
Any advice gratefully appreciated
