Hi DH, DD and I are travelling In September to Singapore and then on to Sydney. I know the flights will be difficult, but what I'm really wondering about it the jet lag at the other end?! Our flight to Singapore leaves London after 7 and arrives at 3pm local time. We are here for three nights before our Sydney flight which leaves again around 7 and arrives at 5am local time. If we let her sleep on the Singapore leg will she be up all night? What happens if she doesn't sleep at all? Worried! Does anyone have experience of this? Generally DD sleeps 8pm until 7:30 (although she is standing waving at me just now - damn you mmr!)
