I wish someone had told me this before I had Little Bit. This advice is more for stay-at-home moms than working moms. Only because working moms are able to socialize with co-workers.
After you have a baby and have settled into being a mom and begin getting into a routine you seek out friendship. The current single-friends (or marrieds without kids) can’t identify with who you are now that you have a newborn. The only thing you can talk about is amazing things he/she has done and the poopy diaper they had the other day. The only thing left to do is to find new friends, mommy friends.
There’s bulletin boards all over the place for moms in local areas or even global mom groups. They’re fantastic to join if you need advice, share stories or pictures, and just have a common camaraderie with women who understand (for the most part).

Here’s my advice. It’s super to join a local group and have playdates, and it’s nice to consider these women as friends. But do not hang out with these women on a regular basis when the only thing you two have in common is your children’s age. That is not a basis of an everlasting friendship and it only leads to disaster.
Find a woman (or two, but not more than 3) that you have a similar set of beliefs on raising your children. However, you may find that gem of a lady who may have a complete different view on raising children but you equally respect one another for it. You want to find someone on your own level. Don’t settle for someone simply because your children get along. To help ease into motherhood and beginning your SAHM career, it’s good to meet up once a week.. have lunch at eachother’s house or even out. But go out and do something.
If you have at least one lady friend that you can develop a close relationship with and respect her opinion on advice with kids, then you have a super match. More than one woman and you get that strange triangle chumminess which often leads to backstabbing, hormonal conversations, and fights on who’s hanging out with who more often.

Also.. put yourself and the baby on a schedule. If you do the same thing everyday, it becomes a routine and the baby adapts to it. But just as the baby needs a routine, you do too or else you get into a rut. Maybe on Mondays you see Jennifer (your super-super friend), on Tuesdays you photograph the outdoors, on Wednesdays you plan your menu for the week, etc..
It may seem mundane and a little silly, but you’ll find yourself looking forward to such things.

Also.. to keep socks together in laundry, put them in a pillowcase.
