DS is 10 months, and his dad see's him 2-3 hours a week if that.
He lives 20 minutes away on the bus, and wants me to take DS to him every other visit (after originally demanding I take him every visit).
I have taken him a few times in the past in a taxi, once on the bus, but have said now that he can come to see DS rather than me and DS travelling.
He can't have him at his house share so the location makes no difference to what is available to do during contact.
I have explained that it is not practical taking a buggy on a crowded bus, especially if DS wants carrying, or is screaming after contact as he gets very clingy and upset during/after seeing his dad.
I have also pointed out that I walk to baby groups 3 days a week, and have to do all the usual travelling that comes with being a parent eg. doctors, shopping so on with DS, and so don't think it is too much to expect him to do one bus journey a week without a screaming baby in order to see DS.
I do know parents are usually expected to do 50/50 regarding travelling, but this just seems ridiculous when he does no actual parenting 95%+ of the time.
