My sister has been calling me, her 3 week old has been waking through the night every two hours...imagine that? And this is her second baby, she is not totally new to this all. She is nursing and then giving baby formula after nursing feeding to"help her sleep'. She had asked me if if I had read Babywise and I pretended to act like I wasn't completely shocked. She is trying to sleep train this little NEWBORN! Ugh! I just want to give her some solid information. Her difficulty nursing is no surprise as even before baby was born she had her doubts. She wants to start only nursing twice a day, rest of the day give formula and things her milk will stick around.
