My 4 month old boy has a mild reddish left eye and tears/ watery alot. Some crust, but we think is normal. It s been like this for three months! Is this a blocked tear duct or something worse? Also, we just switched from a crib to a pack and play for sleeping arrangements for baby boy, since then , we ve noticed red bumps/ pimples on his head only! He will have them for up to five days, then they go away on there own, almost like bug bites, but don t think they are. Is it possible bumps are allergic reaction to new mattress/pack and play? Thanks - jake
