How much sleep is too much? The nurse said to call if baby (2 months) was lethargic. He has a bit of a cold. Congested, and he keeps getting choked on the drainage and puking/gagging. I've been posting about whether to wake him up or let him sleep, well last night we didn't have that choice to make. He woke up every 2-3 hours to eat and went right back to sleep. It's 10:31 a.m. right now, and he woke up to eat at 9 a.m. and had another choking and gagging episode and went right back to sleep. He hasn't been awake for more than 20 minutes since last night around 11 p.m. Is this considered lethargic or is he just sleeping because he doesn't feel good?
