My little one is 7 wks and I've noticed our feedings take about 20-30 min he drinks 4 oz every 3 hrs with his last nf at 7 and a df at 930 he does sleep from after his nf(say 730)until 330-4 am sometimes even later. He falls asleep while drinking during his last feeding and I try not to be loud because after that I put him down so I'm scared ill wake him up & then he won't settle. Am I wrong should I keep him fully alert eyes open at every feeding except of course the df? Is a bad habit forming by letting him eat that way?
