It's time to buy a bigger nest!

Looking cool and causal in blue sweater, black jeans and comfy boots, January Jones took her 5-month-old son Xander (and his nanny!) shopping for a big new home in LA, on Friday afternoon.

The Mad Men star gave birth to her first child last September, and while she's not yet ready to reveal the baby daddy's name, she is anxious to leave her bachelorette pad behind!

Jones is currently in search of a home in an exclusive area of Beverly Hills that will be big enough to accommodate her growing family -- does this mean there might be more babies in her future?
