My DS 5.5 month old does the same. Grumbles and chatters away but I read that it is important for speech development. So I would not worry about it. I find it hilarious and cute!!
Sleep disruption is there too, since he rolls over effectively and now has started crawling too. So I guess thats normal since there's so much going on in their lives and until they master a particular skill they will keep practising it.
Again even my son would not STTN. We are still up twice a night to feed. Again, its the Bangalore effect, It has got so cold that my son wnts to snuggle with me all the time:)
For entertaining, try this: Fill a plastic water bottle (preferably colored) partially with water. And roll it in front of your child. My son can spend all day just running behind this water bottle since the moment he goes close to it, the bottle rolls away..
Try putting a baby mirror in front of him. They love looking at the baby in the mirror.
Use lot of rattles and some plastic spoons and bowls.
Keep rotating your toys..
Hope some of this help..My son was very bad at self playing until 4 month old. But now pretty much plays alone and keeps himself entertained.
