We started sleep training our son on Saturday. The first night it took 1/2 hour of crying before he put himself to sleep and slept through the night. The 2nd night he didn't really cry just whined for about 40 min and then slept through the night. I was wondering what other working parents do when other people watch them. Should they follow the same methods? My sister in law watches him during the day. She put him in the pack n play and he cried/screamed for 1/2 hour...she couldn't listen to him cry so she picked him up and cuddled him. He fell asleep. Did her doing this ruin what we we've been working on this weekend? How do you handle when other people watch them during the day?
