My DD is 17 and had her baby (dgs) just before Christmas. Unplanned pregnancy and her then boyfriend (dgs's dad) wanted nothing to do with them both. She only found out that she was pregnant 7 weeks before dgs was born.
The first few weeks was fine and with support from myself and her older sister, she was looking after him with no issues. The last month or so I think the novelty has worn off for her. She frequently goes out with her mates and leaves dgs with me without asking if it's ok. I've told her I don't mind babysitting if it's prearranged and I don't already have plans but several times now I've had plans and she's gone out without asking if I'll look after him. I've then either had to cancel my plans or take him with me. I try calling her to come home and she won't answer her phone or texts
I've tried sitting down and talking to her but it goes in one ear and out of the other. She says she'll stay at home more then doesn't. Last night she went about 3pm and didn't come back until early this morning. Didn't answer her phone in that time. So I was left looking after dgs all night.
How do I get her to step up and start looking after her son?
