Do you know that babies sleep more than 16 hours a day? Oh yes, for new born at least. But they do wake up after 3 to 4 hours just to eat. Andi has been doing it for a month now. She sleeps most of the time and wake up just to eat then after 30 minutes to an hour will go back to sleep. This is just ok during the day, but a night this will surely ruin your sleeping habit. That is why, I learned to watched TV at 3am. No time to watched TV or do something I want during the day because, you will learn to grab every minute that she is asleep to do household chores. And of course to take good care of my other daughter.
At one month she is now eating 4oz. of milk in just one gulp! (not literally ha?, she drinks it straight until the bottle is empty!) She is a good eater and a light sleeper. Good thing, I have my mother in law to help take good care of her during the day, while I get some zzz for an hour.
I'm not so sure until when this sleeping pattern will last. Hopefully it will change soon !
