Some feeding advice please

So little one is 7 months old and up until recently was loving her solid foods! Recently she has learnt to blow raspberries and in turn means during meal times she likes to blow raspberries!

Do they grow out of this or is there a way to stop it? Weve tried having next spoon ready, distractions, not looking at her but we still end up covered in food and with her not taking many calories in
