Now that your Daddy is swift at responding to your demands for him to click the clicker and dole out the treats, you can try softening him up at bedtime! Yes, I know it's a big step but it's very worthwhile as he's pretty big and takes up quite a lot of the bed... ;)
You have already established that your place in bed is right between him and Your Mummy and bedtime just doesn't feel right to him without your presence, now start to rub up against him on your way up the bed to your favourite cuddle spot with Your Mummy. A few headbutts can go a long way to making him give up extra bed space to his new "snuggle buddy". Just make sure that you give him a few extra rubs and headbutts when he's been extra good and warmed up the space he's willingly handing over to you and soon you'll have a well warmed and softened up space to occupy between your beloved Mummy and your Daddy. Oh yes that's right everykitty, you must keep them apart or they'll forget to focus all their love and attention on you at bedtime! If you're like myself and have the additional pleasure of sharing your home with one of your very own siblings, or even a co-operative buddy, (that's NOT how I'd discribe Tigmut'hep, ok!) you can get them to help out by holding down their favoured person (even if that also happens to be Your Mummy, just as long as you and they don't vie for the same part of Your Mummy, it'll work) think of the big picture here and go for every square inch of bed space you can... Once this has been achieved life will be so much sweeter and you'll be able to sleep comfortably between your beans all night long if you wish, without fear of getting squished in the process.
So there you have it, a Daddy who gives you treats on command, who can't sleep without you and who gives you plenty of room in the bed while keeping away from Your Mummy and all you've had to do was acknowledge his existance and let him fuss your glorious furs while on occasion giving him a few headbutts! You're ready for the final steps on the road to making your Daddy Better! :)
