Ok, before you flame me, this is kind of an emergency and I won't actually go if I'm told it's unsafe.
DS has chickenpox quite badly. Spots everywhere, very sore. I have just come on my period unexpectedly and have nothing at all in the house. I haven't got anyone that can drop anything round as DH is at work, no friends that are not busy with stuff right now.
WIBU to put DS in the buggy with the raincover on and nip into the shop quickly? I would leave the raincover on in the shop too and obviously wouldn't hang around looking at shampoo or anything!
