Oh, how exciting - we are going to try for bub number 2 in March (we have one little frosty patiently waiting). FWIW we fell pregnant on our "first go" at IVF so don't be negative - it can and does happen, just as other times it might take a little longer.

In telling your mum, well I would think (hope) that she just might be excited about the prospect of being a grandma and forget all about how narrow-minded she has been. We didn't tell our family until after we had had our first appointment and had actually started treatment. Up until then it was something that was just between us.... I mean if we were doing it the old fashioned way I certainly wouldn't be telling them what we were up to (hehehe!). Like RhiChiChi says, babies do have a way of changing people.

The only other bit of advice is: just be there for each other. DH was my rock who kept me sane.
