S.S.
My baby is 8 1/2 mos old and she does something similar. We put her down at around 9:30 pm and she sleeps through until 8am. Periodically through the night she will have the wimpering and putting the paci in subdues it. It will happen at around 2 am, then again at 5 am. She's been in her crib since she was 3 weeks old and I just get up out of bed and walk downt the hall to her room, and give her a little pat. I've never had to physically take her out of the crib to soothe her so I didn't think it was a big deal. It seems like teething to me. She doesn't have any teeth yet. Could be dreams too.
No advice really, but I would put the baby in a crib ASAP.
