my ds is 11 weeks old but only 3 weeks old developmentally as he was 8 weeks premature. He feeds every 2 hours and sleeps the rest of the time. Should i be playing with him and trying to stimulate him with his toys. Today I put him in his basket after feeding and he looked bored/sad so I took him out again. I tried him with his toys and he didn't even look at the flashing lights/music etc just stared at me.
