I agree with Snacks hun, it really is up to you when you decide to cut the feed. Izzy is 8 mths and still has around 7-8 on average! Someof those are really quick but it works at the moment. I know they are all different but Izzy has 3 solid feeds a day with a snack like yoghurt or a rusk in the afternoon plus all those feeds, so I think it really is a case of doing what you think works best.
If she isnt interested I would be offering her the feed a bit later on and maybe thinking about introducing another solid feed.
Good luck with it!!
