Is 8M too early for self-weaning?

Hi there! I was blessed with a very efficient chomper - from day 0 of BLW at 6 months old she was drinking and eating eagerly and properly, with little fussiness. She's gained a lot of weight, jumped up to another scale. Right now at 8 months old she is eating three solid meals a day.

We were and still are fully breastfeeding. I am offering milk first, keeping solid feeding well apart from actual breastfeeding. She did increase night feedings slightly when she started to get a combo of increased mobility and teething.

For the past week I've observed that she was shortening breastfeeding time. Innitially I thought it was because she was too distracted, but yesterday and today she did most of her feedings under 3min. I've tried to feed her in complete darkness and she still decided talking to me was more interesting. Night feedings are ending under one minute, so she's clear she's not interested in those as well (just whining).

It came to a point today where I questioned myself - is she starting to wean off?

So, wise BLW reddit folks - isn't 8M too early for self-weaning? Should I stop solids all together to force her to prolong breastfeeding? Or it's fully ok and I should just be happy she's round and healthy?

Edit for additional info: MIL was feeding her pumped milk yesterday, so I know for sure she's eating almost half the usual amount, not just being more efficient.
