She'd decided, as long as she (and I) were well, to continue so that she wasn't sitting at home worrying.
Mum endured a small speach just before she left and her collegues kindly gave her some gifts for me - nail clippers, bowl and spoon, baby gym, hair brush and comb, and teething rings. Also, she received a box of chocolates and a baby bottle of rose wine to celebrate my birth (when I arrive).
