Eating regression

Has anyone else’s baby had an eating regression? Any tips? He used to get on really well with purées, would eat quite a bit, and was making loads of progress with finger foods. He was actually swallowing and chewing things. He was actually doing so well I decided to cut out purées and go on to BLW. I noticed he was eating less of his finger foods and was barely interested after that, so I trialled him out with some purées and he wasn’t as interested in those either - he would only have a few spoonfuls and wouldn’t care anymore. He’s also gone back to acting like he doesn’t know how to eat finger foods! I gave him an egg earlier after no finger foods for a few days and he bit off a chunk and wouldn’t chew it, swallow it or spit it out, just like he did when we started weaning 1.5 months ago. I know this is normal but I’m at a bit of a loss on what happened 😅
