I know the birthdate and last name of baby I am searching for but it doesn't come up in the search. Other babies with same last name and birthdate come up but not the particular one I'm looking up. How can I search? How is this done?

It sounds like the parents didn't list the last name properly. Contact them and ask them what last name they used and try again.

It's as if they didn't put the last name in at all. Is there any way to do that?
Thanks

It could be they didn't list their last name at all, yes.

Please contact the parents and ask them for the direct url.
