I'll add my 2 cents as if I wasn't the OP.
I think if i had read the first post I would say that I can totally understand wanting to stick to the schedule set by the MW if that's what the mom chooses. First, I happen to enjoy and look forward to MW appointments. I don't feel like a watched pot and I don't feel invaded at all. BP, fundal height and baby heart beat is all I've had this pregnancy (other than a very early resus factor / iron blood check) and it's no big deal to me. The checking in helps me focus a little on the passing of time and helps remind me just how fast time is going by. In addition to enjoying the visits I would say that if the MW has chosen a prenatal routine that she feels is best I would wonder how much flexibility is built into the protocol before things don't feel like they're enough. I suppose that's different for individual MWs and their relationship with individual clients.
Interestingly enough (because I get the vibe some that midwifery is the "anti-OB" choice) - I've never been to an OB (well, I have had a hospital transfer but that's a slightly different issue). My last doctor was my pediatrician. I don't have a framework to compare midwifery to OB care. I guess I mean that I'm not looking for care that's unlike an OB - I'm just looking for care that's right for me. I did not choose midwifery because I hate OBs anymore than because I wanted "hands off care". I want thorough, thoughtful, professional care. I don't know why HB MW follow the 4/2 week protocol but mine did/does...I expect that my MWs chose protocols that they felt were best for mom and baby...and MW. At least that's what I would hope were their reasons. I can't imagine any of them doing things that have little value just because that's the way it's always been done.
Of course I would also say that a MW is going to miss visits from time to time and it's completely unreasonable to expect that every meeting will happen as planned. I would even say that the occasional "no show" is par for the course. BUT, I would also say that I think that should be rare and if it happens it's reasonable to expect a bit of extra attention to follow up. A 4 day delay in getting back to a mama following a no show is not ideal and I wouldn't expect any mom to be totally relaxed about that.
I do appreciate hearing from those of you who don't really want or feel you need as frequent prenatal visits as well as hearing the perspective from some MWs about what you do when you need to cancel a visit. I do think it's 100% reasonable to not want to go as often and I also think postponing till the following week if a MW needs to cancel is a reasonable soluton.
