This is probably a really stupid question....
when do babies start crying tears? I ask because in the last week my dd (13 weeks) has started to cry real tears and I was wondering whether she's more upset now than she used to be, or whether some physiological/developmental change has occurred.
It may be coincidental, but she had her 2nd jabs last week. I've noticed that on each occasion she has seemed fine at first, but a couple of days later has backtracked on some recently acquired skill - head control worsened last time, has stopped cooing this time. (hopefully temporary like with head control).
Any ideas mumsnetters?
