Help! Just flown back overnight from San Francisco with 6 month old and 3 year old. Toddler kept up until 10pm and now out cold. 6 month old slept from 8pm until 11pm and is now WIDE AWAKE!! DH away on business - of course - so am home alone and going bonkers... Calpol? Medised? Have just given some banana mush to create full tummy. Any other tips?
