My question is HOW did Walt give the poison to the kid without being noticed by the Mom or anyone else, and HOW did Walt get the cigarette out of Jesse's pack? In the amount of time needed this seems a bit of a stretch

Spoiler!

Actually, the kid wasn't poisoned by the tainted cigarette, it was the Lily of the Valley plant. At the very end of the last episode, they panned over to a planter on Walt's patio near the pool. It was full of Lily of the Valley. How else was Walt going to keep Jesse from working in the lab? How Walt did it is beyond me.
