Head full of rocks?

We would have to describe Mac's neck strength/head control as "poor to poorest". Or, on a scale of 1 to 5 with 1 being lowest, we would place it -for a boy his age- at a 1 (only just).

That said, he is -as of today- producing real tears. Who needs to be able to lift ones head when you can get whatever you want by quivering your bottom lip and letting the tears flow?
