I'm at my wits end. I need help!!!

Okay now my DD#1 is going down nice and early now my DD#2 is now not sleeping. For the past 6 weeks or more DD was sleeping 830-between 4am and 6am until Wed.

Wed night I had a committee meeting for DD's nursery school and b.c DD#2 won't take a bottle only I can put her down at night so she went down at 930 instead.

DD will be 4 months old tomorrow. She has been rolling since 12 weeks but never at night or at naps only when playing during the day. Starting Wed she started moving all over the co-sleeper (not rolling but pushing around with her feet). So she would end up in a corner and constantly wake herself up.

So we said this isn't safe and we went out and got a portacrib. Right now the girls are set up to share a room - but we are in contract on a house and are moving back to my hometown. The girls will have their own room and we hope to move end of Oct or beginning of Nov. Since she still wakes at night I don't want to put her in with my 2 year old who is a light sleeper.

2 nights ago she started rolling so I can't swaddle her anymore (I only swaddled her at night). Now she not only is waking herself up with her hands but she is rolling and moving around her crib like crazy. It is bad enough when I put her down on the floor for a diaper change I go to throw out her diaper and she is across the room (no joke). She is getting herself caught in the corner of the crib (head in the corner) so she has no place to roll or move and needs to be rescued. I put her down asleep and within 1 hour she is crying for help. I have been woken up every hour for the past few nights and haven't slept at all. She will only sleep quietly in my arms - I can't sleep with her in my arms all night b.c I don't think it is safe.

If you are still reading please help. This wasn't as much of an issue b/c DD#1 so I'm at a loss.

Etd to add the other reason we switched her from the co-sleeper is b.c she is starting to sit for a few seconds at a time so we felt it wasn't safe anymore and she kept pushing her face against the non mesh side of the co-sleeper.
