Looks like a healthy girl to me, head is to small, maby a adolescent male but not a 9 month old, here is my male at around 4 months right when his head exploded with growth before his body. I guess it could be a very feminin boy but I doubt it, try catching the croaks on a recording and post them. The frog croaking in that clip is a juvenile boy that's why it's a higher pitch, a 9 month old boy produces quite a bellow lol
