Never rains but pours Angel. Hope your mum recovers soon.
Back wise 6 week intervals is the gold standard. I suppose the way to think of it is if you take things a little easier on yourself now you will reap the benefits in the long run. Its a shame you haven't any other family members that can help out with bubs now & then.
Well done on getting back to the packs today though, that is a battle all of its own. One day at a time is the way to go at the moment xx
