ruthlouise, whereabouts in the UK are you? Someone from your local SANDS branch might be able to help you with some ideas for Isaac's funeral. I am in SE London and could help you if you wanted - this is such a horrible task.
We had Away in a Manger, the reading from Matthew where Jesus asks for the children to be brought to him, and this poem, read by Tom's aunt:
For a Child Born Dead, by Elizabeth Jennings
What ceremony can we fit
You into now? If you had come
Out of a warm and noisy room
To this, there'd be an opposite
For us to know you by. We could
Imagine you in lively mood
And then look at the other side,
The mood drawn out of you, the breath
Defeated by the power of death.
But we have never seen you stride
Ambitiously the world we know.
You could not come and yet you go.
But there is nothing now to mar
Your clear refusal of our world.
Not in our memories can we mould
You or distort your character.
Then all our consolation is
That grief can be as pure as this.
I felt very attuned to the unsentimentality of the Jennings poem. It was what I wanted. Not all parents are comforted by the idea of angels etc although I know it helps many people.
We had a small service at the church and then at the crematorium we had In Paradisum from the Faure Requiem and a short prayer. Just us and the priest there at the crematorium. Close family at the church.
If Isaac is in the Mortuary then they will have taken good care to keep his body in good condition, but I am sure that is not the only thing worrying you about going to the chapel of rest. I am not sure if this helps or not but I think undertakers will tactfully deflect you from seeing a body again if they think it is likely to cause particular distress. Our very sensitive funeral directors did this for us - and I was happy to be guided by them.
If there is anything I can help with, please CAT me (usually I am Marina). I could ring SANDS for you and get a copy of their very helpful, honest booklet "When a Baby Dies" sent, if that would help.
Thinking of you all at this most dark of times. I am so sorry Isaac died.
