Ok, had to change how we were going to announce it as dh wanted to tell family now. So instead I wrote a santa letter on the computer (with xmas border and pictures) and put in it -: Dear Santa, We have been really good boys this year. We sometimes fight but only a little bit. We are going to write another letter soon but wanted to ask, if you could please bring our new brother or sister something this christmas so that we can give it to him/her in July. If we wait till next Christmas, it will be too late. Thank you Santa. Luv ds and ds xo
Then popped it in an envelope with Santas details on the front. When we got to mums/inlaws we just went, 'the boys have written a letter to Santa, have a read, its really cute' or something like that. It has worked so well. Have found it a really wonderful way to announce and just seeing the faces drop when they get to a part that it actually clicks - lol.
Anyway just thought I'd share. xo
