First of all, no matter whether the child is born or not, blessings and congratulations are given to the two of you. Seeing this father thinking of a name for the child gives the child full of expectations and joy. Then, the suggestion I give is Li Tanxin and Li Tanyi. It can have the same sound but different characters. I came up with the name mainly because it sounds nice and has a good meaning. Or should the parents think of it for their children? Thank you
