Dreamfeed advice

Hello I am hoping for a bit of advice if possible!  My little boy is 6 and a half months since birth we have done a 'dreamfeed' at 1030.  However, he has taken up a new thing during the night of waking up and gabbling and laughing for a bit.  Adorable yes but also it's not hunger (trust me we know when he is hungry).  Tonight we are considering dropping the dream feed in case it's actually becoming counterproductive as in he has to digest another bottle through the night. 
He takes 8oz each feed at 630am, 1030am, 230pm and 630pm is this enough? He is also having some puréed foods and baby rice with the start of weaning etc.  Obviously if he wakes up in the middle of the night hungry we will feed him immediately
in lieu of not having the dream
Feed. Anyone have advice as to whether we are being too hasty or if it's the right time to drop the dream feed?  Thanks in advance!
