I'm such a dag.
You know how I said DD hadn't gained any weight...? I got all confused about how much she weighed the last time... Went again today and she was 200g heavier than on the other scales. Thought cool, it's a gain. Looked in my book and realised that she's actually 1.2kg heavier than nearly 2 months ago
So never mind me. At least she's putting all that night feeding to good use
