Hi space,
Your are entitled to time off for ante natal appointments and then the two weeks when baby is born but I think that is it. Once you have had your two weeks any more time off will probably be unpaid and companies arent obliged to take things into consideration such as the mother needing help with a sick baby. If baby was taken into hospital, they would probably be more compassionate but it still likely to be unpaid. I have read that as the babys grandmother was the one who took time off work to help? If I have read right then I can understand the company not being happy about it as it shouldnt fall to them to allow her time off and she was lucky to be given anytime at all. Had it been for the father, they may have been more understandable.
