My LG is is 3 months (15 weeks) and I feel like she's hardly awake. She sleeps from 7pm-8am then has a 2 hour nap from 9. She then wakes up for a feed and hardly ever manages an hour before she's asleep again. I stimulate her as much as I can. It's a real struggle to keep her awake for a while (at least 1.5hrs) before bed time but we manage it, usually resulting in an overtired baby by the time we get round to bath bottle and bed.
Can anyone think of why she might be so sleepy? I thought she'd be out of this newborn phase by now.
