Attach several toys to the side of the cot (only attach toys intended to attach to the cot) for baby to stare at and eventually reach for; there are stuffed toys that can wrap around cot railings, for example. An unbreakable plastic cot mirror will pique baby’s interest as early as the second or third month. For a long time, baby won’t know who that is in the magic glass, but if baby smiles, the face smiles right back!
