Food w/o sitting up

Kara • Married 🇨🇦 SAHM Girl 09/09/16 -x- Boy 08/29/19 Waiting to TTC #3

I will be doing baby led weaning to introduce food to my daughter.

She will be six months old soon and she shows signs of being ready to eat but she doesn't sit up on her own.

She can hold herself up in her highchair because it has a high back support.

Should I wait until she can completely hold herself. Im not in a rush to feed her solids but she's so interested in eating
