Oh Sarah. I know what it's like. The midwives in the hospital had me in a COMPLETE panic about weight when DD lost 12% of birthweight by Day Three even though she was 3.9kg when she was born. It took her 3 weeks to get back up to birthweight and that was WITH formula - we had huge problems feeding not helped by the complete panic they'd got me into about her losing too much weight.

Anyhow, she has gone from the 90th percentile at birth to about the 30th percentile pretty much from thereon. For me, there was a pretty logical explanation - I was borderline gestational diabetes and my placenta was apparently huge so she was a big baby. Mind you, it took ages for that penny to drop with me because I was only borderline GD so wasn't being treated for it and I don't think it would have been in my medical notes so no-one would have bothered to ask me IYKWIM. Anyhow, genetically she wasn't really meant to be that big so the percentile drop is just her getting back to where she's meant to be. Luckily, my MCHN has NEVER made me worry about this - she just says that some people grow big babies and then they adjust back when they come out.

Obviously I agree entirely with what the others have said - trust your instinct, if she's happy, wees, poos etc. etc. I'm SURE all is well.

My friend had a similar experience with an MCHN who banged on about not gaining enough weight, low supply, the usual stuff. Anyway, she was completely wrong - his slow weight gain was nothing to do with a low supply. A lactation consultant diagnosed a tongue tie. It might be worth ruling something like that out , just in case.

Maybe don't go to a weigh-in and see a lactation consultant instead.

MCHNs really carry our heart in their scales sometimes so don't subject yourself to the half-baked theories of people who don't know what they're talking about. It makes me so mad that they don't realise the impact that their bad advice has on us mums. I was distraught by the thought that I couldn't give DD what she needed and my friend was also in tears when there was absolutely nothing wrong with her supply. Grrrrrrrrrr. And they wonder why we google stuff instead of listening to advice!!!

Sorry, rant over now.
