Naomi you are kidding aren't you? Are you the god-mother? I have never heard of having to dress in theme for a Christening. When our children were christened the god-parents and grandparents just wore nice smart clothes like you would to a church do like that anyway.
As for not appropriate to put up pics. well!! I have Annabelles picture in a frame above my computer in my corner of the loungeroom. I also have her in a different picture as my desktop pic on the PC. A friend (aged 64) told me if I had Annabelle as my desktop pic I should also have my other children but I replied I can look around anytime and see them but I can't just look around to see Annabelle.
I have made cross stitch name plaues with angels on them and sent them to a few ladies around the world I have got close to and in all cases they have put them up on their loungeroom wall or their own bedroom wall. They are a reminder that they have a child and that child was born on 'whatever the date is' and is in Heaven, but they are still their child and the parents are still parents. We also run a Mothers Day card exchange even for those who have no living children because as a mum they were still pregnant, felt their baby growing and kicking and then had to give birth. A silent birth is still a birth.
Annabelle was buried wearing an heirloom Christening Robe that MIL had kept for years. Tash put a small teddy bear in with her, Nic put in a chocolate abr caleld Heaven, I put in an Eeyore soft toy with rattle I had already bought for her and my best freinds 12 yr old son put his small Bible in with her. I wrapped her in bunny rugs and lay her on her side like I was putting her to sleep in her bassinette. Then the lid was screwed shut.
Once her brass plaque arrived for her grave we went down while it was laid down and I was actually allowed to be the one to lay it and glue it in place.
So many memories and I have rambled again.
I am so sorry any of us have to be here and in the situation of TTC again or hoping with a new pg and all the worries.

Hugs
Jude
