Is there anything you can do to make the chances of conceiving a boy higher. we have three girls, and would like a boy, is there anything we can do?

Not specificly: It is the swimmer(sperm) who gets there first that determines the sex of the baby. There is no special position, tea, day of the month or whatever else you heard that makes any difference.Some fertility centers offer ivf techniques that may increase your chances at gender selection but are expensive and not 100% successful.

Congrats!: Congrats on healthy kids! there are lots of rumors, but no good science about what will make you more likely to conceive a boy or girl sorry i don't have more encouraging news for you, but most of the rumors won't hurt anything to try, so see if any sound like they'd be agreeable to you and your partner and give them a try! best wishes with your family for health, love and great lives together!
