thanks for your replies.
I guess I was also worried since if he sleeps for so long that I will be so engorged in the night.
He sleeps in the attempted side car (toddler bed) that is beside our bed (since toddler sleeps in our bed). SO when he sleeps so long, I just bring him in to me and he stirs and accepts the breasts without difficulties.
Should I continue to do that or just let him sleep the night away. I havent figured out how long he will go if I havent 'stirred' him (so to say, not officially fully waking him up).
Wish my toddler could sleep long stretch and learn from her brother. heehee. (she never slept long...always was 2-3 hours stretch and still wakes up frequently in the night).
My mom advises me that I should 'never' wake a baby. Since I am teaching the baby to wake up in the night.
Thanks for your advise and tips.
