Heheh.
Mr W was and is the same way. He wants someone around all the time to interact with.
Here is how his day went at 6 mos.
4 AM: Wake up and play with a toy in the crib. Get bored. Start to scream at the top of your lungs. Mom or dad arrives, attempts to feed him. He wants to play with his toys. Plays with toys until 5:30. Wants bottle. Goes back to sleep.
7:30 AM: Wake up and immediately cry for help. Another bottle. Wants TV on. Sits by self watching TV for an hour or wants books read to him for an hour. Babysitter arrives. Coos all over her. Points to front door indicating desire to go outside. Outside in stroller for two hours.
11:30 - Short 20 min nap. (That's it) Plays with toys for an hour. Time to go outside again, this time to stroll around the mall for two hours. Smiles at everyone he meets.
2:30 pm - Visit chicken place where he eats his favorite chicken and sips juice from his own cup.
5:30pm Dad and mom arrive home. Dad cooks dinner. If he is not on the counter in the boppy seat and gets to watch he goes nuts.
6:30 pm He goes into harness for 1-2 hour walk around the neighborhood. Smiles at everyone he meets.
8:30 pm - Gets last bottle, whines and cries for an hour when put in the crib.
11:30 pm - Wakes up again.

It will never end and you just have to reach some sort of accommodation to where you can stay sane.
At 16 months, he is still exhausting to be around, but after I had a long talk with him at 12 months, he gives us some time to ourselves, if we promise him he'll get to do something. He still throws his fits, but they are less and less.
Either DW or I spend 1-2 hours a day ( in two sessions) with him doing directed activity - like Starfall or music and his babysitter does the same thing. We usually stop because one of us is bored, not because he has lost concentration. This has given him the "input" he seems to crave and has smoothed his moods.
His trackball mouse arrived today and this will hopefully make him more independent and give DW and I a few more minutes to decompress.
