Adding a child to household

I need to add a child to the household of her parents. The child was born in 2016 and according to her paternal grandfather was blessed by him in Heber. When I search for the membership record with the child's name and DOB there is no record found. I could create a record, but I'm worried about creating a duplicate. I have verified the child's name and DOB with the parents. Any suggestions would be much appreciated.

At this point I wouldn't worry too much about a duplicate. If it's not pulling up by name and DOB, it's probably not there. Odds are the blessing wasn't done in the home ward. The ward it was done in didn't create the record for whatever reason.

I'd go ahead and create it. If not done before age 8, then it can't be done until the child is baptized.

If it turns out to be a duplicate, it can be fixed up easily later.
