Hi, been lurking for a while, but decided to post for advice. It's on behalf of my dw, who is too tied up feeding most of the time to post!
Our dd is 5 weeks + 3 and was 6 13oz at birth - this dropped to 6 5 oz and gradually crept up (4 days ago was 7 1 oz) but so slowly that she dropped from 25th centile to somewhere between 2nd and 0.4th centiles. Always gaining, but never more than about 60g (2oz ish) a week.
She's feeding well (every MW or HV has commented on what a good latch she has) and she feeds often - feels like constantly during the day - she rarely sleeps during the day, but if left to her own devices would gladly sleep through the night (we don't let her go more than 4 hours - she never wakes herself). We never let her go more than 3 hours during the day on the rare occasion that she sleeps, but she often wakes within the hour, hungry. She posits a bit, but rarely any more than a mouthful or two (often an hour or so after a feed). Plenty of wet nappies, and the poos were very frequent until recently when she went a week without one (though it was soft and mustard coloured when it came). Other than that she is happy, strong, alert often, and was smiling (sporadically) from 4weeks.
We noticed that she tended to suck and swallow a lot for the first 5 mins or so of a feed, and then get in to a pattern of fast sucking (with no swallows heard) - often for 20-30 mins - she also tends to fall-asleep mid-feed. We tried breast compression and this improved it a bit, but only for a minute or two, and then the same. Still with no improvement on weight gain. If she finishes, then wants more within, say 10 mins, we offer the same breast first, than the other.
HV is concerned at the slow gain and the 2 centile drop and wants us to (everybody now) supplement with formula, which we are VERY resistant to. HV indicated that she thought we were starving our child if we didn't take some action so, after reading stuff here we decided to give expressing a go, since we are already feeding on demand. We got referred to GP, but GP was v.supportive of us, and encouraged the expressing approach.
So we started off trying to express after each feed to get any fat-rich milk left over, but never got much, if any. So added in an extra pumping session overnight to get an extra feed in (where we could see how much she was getting) and dw generally gets 3oz in one sitting (both sides) and tops this up with another session during the morning to get 4.5oz (ish). DD wolfs this down in about 10mins during the night (when she is normally really sluggish at feeding from the breast).
Now I know that some babies are just "slow gainers" - but what we are worried about is how we know whether ours is doing ok, or whether we are selling her short by sticking to bfeeding when she doesn't seem to be thriving. We don't want to go down the formula route but are worried that her feeding patterns from the breast are causing the slow gain - we don't really want to go with 100% expressing as dw is really enjoying the closeness of bf, and we don't want to lose that.
So, any advice, reassurance? Are we doing ok? We worry lots...
