Night feed help.

My little girl turned 10 months on the 8th and after a few glorious weeks of waking once around 4am for a bottle and going back down til around 7am we are back to her waking at around 12 and 3 for 2/3oz and then waking up at 6am ready to get up.

This is what she was doing til around a month ago when we upped her night time bottle by a few ounces and got away with a few weeks of decent sleep she's then had a growth spurt and is back to how she was before. She's having 8oz before bed so I don't think I can really up it any more and TBH with how little she has when she wakes I wonder if it's really hunger or habit?

Any tips please ladies.
