Transition from milk to solids

First time mom here,,, give me a break

My baby girl just turned 5 months and we just started rice cereal, only once a day, but it’s a start

Should I be feeding her more than once a day? If so, how many times do you guys recommend?

And can I start feeding her baby food? She’s sitting up supported but i guess personally, rice cereal doesn’t sound to appetizing to me.

Or should I be mixing her rice cereal in her bottles? Or should I mix baby food with rice cereal?

I literally have no idea how to start feeding her food but I don’t want her to be behind and only drinking milk at 5 months, did I start to late?

Please help a mom out here

Thank you
