there are a few mum friends of mine who occasionally post fearful status updates/tweets about having to do bathtime for their 2 (or more) kids all on their own without help of their DH/DP/OH.
Surely this is not a big deal?! My DH is often not home at the DCs bathtime and I know I am not alone in this for those with and without partners/husbands/whatever.
Obviously an extra pair of hands is useful but it's not exactly a difficult thing without the extra pair...
