8hr flight

Not sure where to post this but is taking an 8 hrs flight with a 10 month old too much? We've gone flying with him before but it's always been a 2-4 hr flights and those have been in the early am so he would sleep for the most part. This flight will be 630am-12pm. It'll have a 2 hr Time change so where I live it'll be 2pm but we will be landing at the city at 12pm. What do you guys think?
