Hi there ...  so sorry to hear your hubby has this cruel cancer ... but there is a lot of things technology are doing, and there's lots of us on here living with it ... you don't say how old your children are, or what cancer he has ... it's just my thinking but l always feel gentle honesty and depending on their age, depends how much to tell them ... we told my 6 year old granddaughter that nanny had bad chest, and was going into hospital , so the Drs would TRY to make nanny better .. she knows I've not got one boob .. because she had to be carefull of early cuddles .. she wanted to know, how l would feed babies if l had no boob  (I'm 63) and because we laugh and l answer her questions, she cool ... 

My teenage granddaughter knew and as her other nanny had had it years before, was pretty calm esp after a cuddle to show her l was o.k and a lot of reassurance  ...  don't know if any of that helps .. but there have been posts from young ones who feel they are not being told the truth, and are even more scared .. there is a thread on the home page and it helps you on how and what to say to children .. give it a try .. 

There will be tears, and they will worry, but if you both look like your o.k ... and even sharing tears with them too ... can bring you all to gether ... it worked for me, but take all the info from everyone and have a chat about the way forward with hubby ... thinking of you all ... Chrissie xx
