Can I use a buccal swab for the child and a forensic sample for the alleged father?

Yes, you can use any combination of sample types, regardless of whether it is buccal swabs, blood, or forensic samples. DNA is the same everywhere in the body.

I will have not problems collecting a buccal swab sample from the alleged father but will have to submit a forensic hair sample for the child. Should I submit hair for both the father and the child?

No. Whenever you can collect a buccal swab or blood sample from a participant, you should always choose the buccal swab or blood sample over any other sample types. This is because buccal swabs and blood samples are not considered to be forensic samples, and thus have a much better chance of working. Furthermore, forensic samples will cost you more to process than buccal swab or blood samples.
