I have a 5 day old boy who seems to be sleeping a bit too long. It's been almost 5 hours since his last feed. I tried waking him up but nothing would work - he is such a deep sleeper! I'm demand feeding but worried if he sleeps too much longer he's not going to feed enough today and in this heat that can't be good for him!

So do I leave him or keep trying to wake him up & what ideas to wake him. Tried changing his nappy, cold face washer etc
