My brother has a baby with his ex. She stopped him seeing his baby for the first 4 months. He then got a letter through from her lawyer saying he can see his baby 2 days a week for 2 hours. But now she has stopped him seeing his baby again. She has also stopped all contact with my mum and dad as well. She goes out drinking and partying every weekend and leaves the baby with anyone that will have her. She is 7 months old and we have seen her a few times and its really getting to him. Is there anything we can do?
