More than 1 brand of bottle

Do any of your baby uses different brands of milk bottles at the same time ? Eg avent natural & tommee tippee I received a few diff brands of bottles for free. So far baby is using avent natural, and thought of getting another set of bottles so we dont have to keep washing and sterilise for night feedings. Should we just use the different brands that we got instead of buying another set of the same brand ? If baby is suitable. Or will the different brands confuses the baby due to different teat feel #FTM #firstbaby
