Husband jealous of of baby

My husband is jealous of our son .... and he told me that he doesn’t want another baby because that means he won’t get any attention and he barley gets it now cause of our son..... I honestly try so hard to give attention to both and my son does get more attention than my husband only because he is a f***king baby so obviously he needs to be fed and changed and other stuff .... I do give my husband attention and try really hard I don’t know what else to do .
