I work at home, and I try to give my 5 month old playtimes during the day, but there are just times I need her to be in her playpen or crate so I can get some work done. If she's in my office with me, she cries and yelps nonstop. Is this just a matter of getting her used to it? Any ideas on how to make it more fun for her? She has chew toys and squeaks in there, sometimes a kong filled with yummy stuff..I feel guilty but have to get work done and can't watch her..
