Hey A., I'm going through the same thing. My cousing comes to my house and watches my 10 month old (12/12/05). But I still feel like he's being neglected. When he was 7 wks old I went back to work and he slept through the night, now he does not, she likely has him napping all day. I come home early every now and then to sneak up and the little guy's pamper is soaked and wet.
But, at least I know her background. I even spoke to my pediatrician about this; she told me not to worry. She said that as long as the baby's basic needs, such as feedings are being met. I won't put him in a day care center until he can talk and let me know how he's treated, until then, I'm sitting this one out...you just can't trust strangers. The good thing is that I start work at 8am but my husband doesn't leave the house until 12:30, so she gets her at noon. My 15 and 13 y/o kids get home by 3pm, she leaves at 6pm whether I'm home or not but from the time my kids get home, they're basically taking care of him and believe me, they do an incredible job for their little brother. Good Luck!!!
