Have you tried asking to see the burial record at the cemetery the child is buried at?
I have found most councils in Ireland have been helpfull when i have asked.
Just to put a spanner in the works( as i normally do

)
I have found that many children's births and deaths have not been registered at the time they should have in Ireland.
One other thing too, i know that all burial records are not 100% correct too. I have found my own father buried in a grave just a few months old , infact it turns out to be one of his brothers ( he was a triplet ) and his two brothers died only weeks/months old. One i have managed to find the other, not yet.
