His sister is so!!!! Irritating!! I have a stepdaughter and my sister in law always try to make me feel like crap! She makes it seem like I put her to the side nd say means things... my baby is almost 3 months obviously I'm on cloud 9 with her . Every time I buy my baby something she message me did you buy jaylah (stepdaughter) something to....if I don't reply she just comes picks her up and take her all day and buys her stuff...im so annoyed with his family ...im not an evil stepmother but in their eyes iam!!! And they've said that I'm nothing to my stepdaughter but someone to look after her !And with my baby they always have something to say. I'm just over it ... And and I'm that type of person that can't speak up or confront them..idk why...i hate that about myself....
