When do I need to worry about my insanely strong and active son climbing out of his crib? He's 8 mos old and can pull himself up (though hasn't yet done it yet in the crib). Do we have to lower the mattress now? Related: Once mattress is lowered, how do you pick up the baby from lying down to take him out of the crib without killing your back??
