Ready for weaning?

My little girl is 4 months on Friday and I think she’s ready for solids..??? She can stay in a sitting position (with assistance) and can hold her head up, she is inhaling her bottle and will drink it in minutes and she’s already on 7oz (I’ve just upped her ozs) and every time I’m eating she will stare at me. I gave her a crisp in her hand to see what she does and she put it to her mouth. (I obviously took the crisp off her after) her hand coordination is great, constantly in her mouth lol

But I’m a first time mum so I dunno if it’s too early or not. Or even if they are the signs of baby being ready ://

Do you think I should maybe try her with some baby rice to see what she’s like??
