Baby in the bed

They always have those child experts on TV who talk about to pros and cons of letting the baby sleep in the parent's bed. At nearly 4 months till birth, I'm ready to put Josie in the other room with the baby monitor. The kid will not let Becky find a comfortable position. One second Becky has it solved and then the antsy child must roam the other side of her gut. Can't this kid sit still? And it's not like we can give Josie a Cherrio to calm her down. The only thing I can do is pull up Becky's pajama top and make the tuba noise on her belly. It doesn't seem to help so much. Although if she gets curious about tuba music, I'll know my weird training had an impact.
