I understand people are so excited and happy that their baby sleeps for long hours & all night but deep down I would be scared ! New babies need to regulate their breathing every now & then so babies being in a deep sleep can easliy suffer from SIDS because they don't wake their selves up to regulate. KEEP A CLOSE EYE ON YOUR BABY LADIES !I'm happy my 4month old still wakes up once at night to eat ,I know she's not dehydrated & she has time to regulate!
