Hello,
I have a DD who is 3.5 yo. Desperately wanted another one but after 3 miscarriages and being 43 now, my options are very limited. Considering IVF through embryo donation (our best chance) but also slowly coming to terms with the fact thay DD may be our only one. I get very sad about it as I think DD would really enjoy a sibling.
At the same time I consider ourselves lucky to have DD as a number of friends who desperately wanted children don't have any due to infertility.
