What is the best Bottle/nipple type for mixing rice cereal?

Baby is about to be 6m now, planning to introduce rice cereal. While feeding in bowl is best would like to know if anyone mixed some cereal in bottle milk? If so what type of bottle/nipple did you use? Pls share thanks in advance

Edited: surprised with the comments. This is for baby over 6m so may be that’s one discrepancy. Also every baby is different so is their need, no one size fits all ppl!! My post was specifically for those who do it to share how they go about/bottle type/any tips and not if this should be done or not.

For the records our pediatrician recommended it, just one spoon (like regular gerber that fully dissolved unlike organic gerber that needs to be fed through spoon) to thicken milk so it stays down and helps with spitting. Apparently there is tommy tippe bottle with specifically designed nipple meant for cereal milk.

Thanks!!
