Ok i have a question about what to do once the baby comes?

hi i am 30w/5 days pregnant with my second and last its a girl i have a 14 month old son who will be 17 months exactly if i deliver on my due date. and i am worried that he will feel as though he is not loved by me or my husband anymore. btw its not the case at all. so once she comes how can i give them equal attention. i am feeling guilty because we have spent money on the girl. here is the deal when i got pregnant with my son we didnt have enough money to paint his room other then a pale yellow its like a off white. but we did get him whinnie the pooh decorations to hang up. and he did get everything new crib,travel system,cloths etc.we are going to wait until he is 5 so he can pick out the theme for his room but with the girl we painted her room pink and gave her disney princcess stickers.and that is going to stick until she is like 7 or 8. and we just got her a new crib and clothes. my question is how do i give equal attention and love to both of my babies and is there anything i
