Gender disappointment

My husband and I already have two healthy girls (7 and 4)

And we just found out from the blood test that we are having another girl. I knew my husband would be disappointed (not that he would love her any less) and he didn’t want to admit it. I told him he can talk to me about how he feels and not to feel guilty because it’s normal and he finally opened up to me about how he is really disappointed and feels like a bad person for feeling that way. I am trying to be supportive by I don’t know what else to tell him. Any suggestions?

We already had a name picked out for a boy and this will definitely be out last because I don’t think my body can handle another pregnancy and birth.
