I think I'm misreading hunger cues . . . my DS is 5 wks old and very fussy. I think it's because I may be feeding him too much. He nurses every hour or so during the day, every three hours on the nose through the night. However, during the day he spits up frequently and is very fussy, especially in the morning. He's usually awake from 5 am to at least 10 am, closing his eyes for about 5 minutes here and there. I don't offer the breast as soon as he starts fussing, but if I try everything (cuddling, bathing, stretching out of the floor, vacuuming . . . not the baby, for the noise! . . . ) for at least half an hour with no result then I go ahead and feed him. At that point, we're breastfeeding because we both need a break! But often he still fusses even at the breast, finally just falling asleep out of sheer exhaustion.
So, we start a vicious daytime cycle of crying, feeding, spitting up, more crying, more feeding, more spitting up . . . he fills his diapers beyond capacity after an hour, and he's gaining weight rather quickly.
He doesn't root or smack his lips or otherwise indicate hunger. During the night, I usually wake up right before he does (weird how our bodies work!), so he doesn't get to the point of crying and he nurses very peacefully and goes right back to sleep after a burp or two.
I have an active 6 yr old DD and a 3 yr old DS, so maybe the house is too chaotic for my newborn during the day? What am I doing during the day that I'm not doing at night (or vice versa) that results in my son's split personality?
