Sons dad very flakey for example not having him this weekend for blatant bullshitty reasons this is common but I'm at my wits end making up excuses 'your dads got to work' etc when really he hasn't he just can't be bothered or better plans have come up. Makes me mad because it then means I have to arrange childcare last minute or tell work I can't come in all the while making him out to be some hard working hero. Also is there anything I can do to get him to stick to his nights (which he demanded)
