I know this is supposed to be a mother-to-mother forum so I hope it's not a problem if a father asks a question. If so, just ignore me.
Anyhow, we generally wait for our son's hunger signs before we feed him. So when we hear him fussing or smacking his mouth at night we get him up and feed him. Sometimes we have tough nights of 1 to 3 hours but usually he goes 4 or 5 hours from start of feeding to start of feeding. Last night he went 8 hours from start of feeding to start of feeding.
Is this sort of thing common for a 3 week old? Should we be setting alarms to wake him up every 3 to 4 hours to feed him or should we just continue to feed him when he's displaying hunger signs?
