My partner has 4 y/o twins with his ex girlfriend. Social services were involved due to them both being drug users and the children were fostered for a couple of years. Both parents are now clean and the children are back living with mum and social services are no longer involved.
my partner has the children on a Saturday 10-4, and his mum has them the same amount of hours on a Thursday (he can’t have them then as he’s working full time). He would love to have them more and during the last social services meeting he said this and his ex said that was fine and she’s waiting to hear from him.
He said a few months ago he’d like them to stay overnight and she said no they are needy in the night, but the kids sometimes stay at their grandparents and aunties house (her side).
He's said he’d like to take them away for a few days this summer within the UK but again she’s said no, using the same reason about sleeping.
He has always paid child care to her and does everything correctly.
What are his rights?
Thank you
