8 month old not interested in solids

Putting food in her mouth and spitting it out is part of the process of learning to eat. Just keep offering it. Milk is still supposed to be her primary source of nutrition so you're not doing anything wrong

Neither of my kids would be spoon fed. I’ve done BLW (just started the second time with my second baby) just put whatever we have for dinner on his tray cut age appropriately and they learnt to eat really well this way. Also means you can eat your own dinner rather than constantly spoon feeding! Only draw back is the mess 🙈 x

Wait for progress. My daughter did the same around 8 months for a week or so. Refused to be fed and wanted to do it all herself while chewing but spitting food out. Bringing food to mouth, chewing and moving food around the mouth and then swallowing and all different skills so to do them all at once is a lot. It can be frustrating and feel wasteful on food but it’s exploration over actual eating. The more they explore the more they learn. It does improve as I’ve found my baby wants to eat but can’t quite get enough in her mouth bless her. They go back to spoon feeding once they realise what it’s all about.
Good luck!
