Hi, I'm new to this, so hope its in the right place!! I'd be grateful for advice, I have 5 yr old grandaughter, my son and her mum split up about 2 years ago ,they are now both settled in other relationships. my son has access to his daughter once a week and every other weekend. My problem is my sons ex partner it seems, is not happy for me to have grandaughter outside of the access my son has, ie I only have her when she is with her dad, she stayed last week for 1 night with me, and cried to her dad when he came to pick her up, asking when she could come again as wanted to see me. I have tried speaking to her mum,(we have previously been on friendly terms)but she is ignoring me when I msg her to ask if would be possible to have grandaughter bit more, Its not fair to my son for me to take the precious time he has with her,tho' he is willing as my grandaughter would miss out otherwise. Obviously for grandaughters sake it would be best to keep everything amicable, but I just dont know what I can do next.
