How frequest with OA and BF?

I have a general question for those in an open and semi open adoption. How frequent are you with your visits with the BF? Especially if the birthmom is not able to see you ds or dd as often as you like? I am sure what's comfortable for us is best, but just curious if anyone has set up an amount of time that you allow... :flower: Thanks for the input.. (i will x-post)
