[Solved] help

hi, i am not a dad but a grandma looking for help for my son, my son currently has a contact order in place however his ex partner has broken this several times, she has refused to allow him to take his daughter on holiday, she states this was because she believed it was myself who was taking his daughter on holiday, which i may add we have previously done on many occaisions with her knowledge and texts and pictures exchanged whilst we were away............mum then 'fell out with me' she regularly falls out with members of her own family for periods of months at a time and during this time stops all contact for my grand daughter with extended family on her own side. my son and his ex split up when my grandaughter was 4 months old they had previously lived with me and i was present at the birth along with my son, after they split my son had his daughter 4 day, 3 nights per week, shortly before her second birthday they had a row and she then stopped all contact. he attended court for the court order. due to his ex partner not wanting any contact with my son myself and my husband have always collected and dropped off our grandaughter in order to keep the peace. after her differance of opion with me in which i was verbal abused and intimadated by both my granddaughters mother and her new partner in front of my grandaughter who was very distressed and crying. my son took over collection however she refused to hand over his child stating he had no right to collect her due to the threats and abuse he recieved the police were called and his child was handed over.

after this incident things got worse and she either refused to answer the door or had gone out. my son has applied to court for an enforcment order, however having been unemployed for sometime he has now found a job, the downside to this being he can't forfull his contact in full due to work and has been informed he can not make any child care arrangements with myself for when he is at work, however the mother can leave her with anyone she chooses. he has a court date for enforcement order but is there any point as it will end up as a variation of contact his ex advised me months ago that once the child started school contact was only going to be every other weekend, my son should have thursday 10 -6 fri 5.00 pm till sun 5pm his ex is demanding that there is no contact with extended family on our side to the point she doesn't even want us to be allowed to take her to the park. our grandaughter is 4 it was her birthday yesterday is very upset and confused. this can't possibly be in her best interest my son did get his contact yesterday but his daughter was so distressed on having to return to her mother she sobbed all the way home. our grand daughter is told that the reason she can't see her daddy is grandma's fault because i break the rules and if we loved her we wouldn't break the rules. the crime i committed that was the start of this fall out was allowing my granddaughter to still have her milk in a bottle at bedtime and whilst i realise she should have been using a cup due to her little life being quite stressful and it being the only comfort thing she had i didn't see it as crime of the century. my son would like residancy but feels this is very unlikely he is distraught that he feels in order to keep contact he may have to give up his job. his legal aid has run out now so it looks like he has no support from any where and mum can do whatever she wants can anyone offer any advice please
