any minimum time between two visits to USA(visitor visa)

[newtothis]

hi, my parents have 10 yr multiple entry visa. they will be staying in USA for 5 months and go back to India and my mom is planning to come back after one month. Is there a minimum time she should wait before coming back here ?

Thanks!
