Hi!
Just wanted to add that our son is much like many of the others who have posted. He is secure, happy, alert, inquisitve, and in love with his world. I attribute this to DH and I attending to his needs so quickly and with such a hands-on fashion from day one.
Now that he is older and can manipulate to a degree - we do things slightly differently. He doesn't always b/f to sleep anymore so if that happens I put him in bed and pat his bum or back until he is asleep. If he mucks up and won't stay lying down then I give him one warning and if he does it again I leave the room for 1-2 minutes. I never stay out longer then 2 minutes and ALWAYS when I've gone back in the room he lays straight back down and usually goes straight to sleep. As I said, I never go beyond the 2 minutes and so far I have never had to leave the room twice. I will add to that this doesn't happen ever night - only the times that he decides bedtime is playtime!
Keep up the good work and try hard not to let the guilt get to you...
