sell the 2 year old. :wink:
does your 2 year old still nap in the afternoons? if so, i would spend the most time trying to teach your 8-week old during that time.
as for when your toddler is awake....
- do a massive babyproofing in the part of your house where your toddler will be while you are with baby & corral them in there
- have some toys that only come out when you are trying to teach the little one to sleep.
- try & get some good interaction playtime in right before the baby will wake up (if you can manage to stay awake yourself!)
- you may want to give your lo a doll of their own to do pat/shhh on. my dd almost does it better than i do now!!!
- install a gate along the hallway where your toddler can watch you from, but can't disturb the baby (even if the toddler screams)
- dvds can be fantastic
