Hi there, welcome to the message boards. They are a fantastic source of knowledge and comfort.
In your question do you mean that DS is having something to eat and then going straight to sleep so is not effectively getting much A time?
When our DD was that age she was only usually up for about 45 - 1hr max and that pretty much just included her being feed and burped (which took about 20mins!) and then a nappy change and maybe a few toys etc.
At this young age bubs don't necessarily need to be playing with loads of toys just looking around and getting used to the environment and hearing, seeing and smelling all the new sites is enough of a 'play-time' for them. So your little one might be ready to go back to bed after a feed, chat and nappy change.
If you post your daily routine I am sure the forum moderators will be able to help you out much more.
Enjoy
