Crib to big girl bed...what's your advice??

OK, so we are prepared for baby #3's arrival with the exception that we are converting Sam from her crib which she hates and refuses to sleep in!! We bought her a big girls bed and have allowed her to get comfortable playing on it, laying on it and with her room. She loves it and knows it is hers. Now, for some reason, I cannot recall how I got my 4yr old to sleep in his big boy bed. He was a little older (2) and it seemed to be easier.

Any advice is appreciated.

Things have been going great other then our little sleep issue with Samantha. She has been very happy and that makes me very happy!! :)

Aidan started flag football last week and had his 2nd practice this weekend. I don't think people know how cold it is here in Iowa. It was 35 degrees with the coldest windchill. All of the little kids froze and half didn't even show up. I pray for warm weather like you EAST coasters are getting. You can't appreciate your weather until you live in the Midwest.

I'm feeling pretty good these days. I lost my plug last week and have had a lot of pressure. I just pray that everything goes as great as it did the 2nd time around and that we have a healthy baby.

Does anyone know of any good playgroups for 15 month olds??
