you could either offer a little bit of something around the 10am feed (best to do it in the daytime in case of any reaction) or offer something at one of your mealtimes instead (the solids dont need to be given with a milk feed)
I give my 6 month old some solid food about 60-90 minutes after her milk feed. Morning, lunch and mid-afternoon, and then her last milk feed is bedtime. That gives her enough time to get hungry for solid food, and then enough time to get hungry for her next milk feed.
We do BLW so it's hard to tell how much she has, but she's putting the weight on and seems happy, so I guess it's enough.
