Because I really can't remember what went down with LO #1...

LO#2 is 1 month old and wakes MANY times at night, may or may not eat and is difficult to get back to sleep. Lately, she's sleeping maybe 45 minutes in the morning, 45 minutes in evening and 4 hours in the middle of the day (waking halfway through to eat of course). Is this long napping stretch during the day causing night wakings? Help please!!!
