My son is babysat for two feeds a week - and gets a bottle of EBM at that time. We have been doing the pausing thing with the feeding to slow down how quick he guzzles and he has been using a newborn teat. But now that he's three months should I be using another teat with the EBM or will that just encourage guzzling? I don't want bottles to be easier than breast

I've also noticed basically he will drink anything I leave - no matter how much! I've left amounts from 120ml to 180 mls and it's all gone. How much is a good guide to leave? He's a pretty solid three month old - almost 8 kilos, and feeds at least eight times a day I reckon.
