Yup ... I do several with the parent 'on site' but not necessarily in program for FREE to get the babe use to be hearing, for me to learn their cues while parent is still around to ASK and so forth and than depending on how much time we have before the mother 'starts work' and takes possession of the space I suggest that the week or two leading up to mama having to return to work that we start coming 'daily' but on a weaned in schedule ... so first days 1-2 hours with mom on call if babe is screaming inconsolable and than work up to stay for lunch, than stay for nap and than full day as normal as they are coping better with each progression this way by the time they are full days and coming full time they are not crying ALL day cause they trust mama comes back, I have learned how to meet their needs cause mama is close by as reference and so forth ... once they are being LEFT here in my ratio without a parent I charge a prorated rate for that wean in schedule from hourly rate, to half day rate to the full day rate.
