Dach,
I believe it is best for Dh to say goodbye & explain that he is off to work & will return (if it's that night at 7pm for instance) say Daddy will be home after dinner, but before your bath (if that fits in with the routine, or whatever your routine is).

If DH will be home at 3pm then find something that you might do around that time each day so you can explain Daddy will be home at reading time, or after the reading time or whatever is happening in your home at 3... (Does that make sense?)


If it's over night or something I think you'll need to maybe mark it on the calendar with a star or sticker & let Yasin cross off the daya & explain Daddy will be home on the star day after your bath or whatever time it fit's in with...
Hopefully it will make it easier... best of luck..

Colleen, as bad as it might sound, kids forget about someone that's not around much fairly quickly... I suggest lot's of extra hugs for Jaykob, as this time is difficult for you both I am certain... hugs!!!
