My husband and I have been married for 6 years, I have one BD (8) who my husband has adopted, one SD(15), and one SS(10). 
when my husband and I got married my SD was 8 ab to turn 9 and everything was great.... now she's a teenage and .... I've noticed that I'm sometime really jealous of her and the time she spends with her dad. 
Saying this makes me feel like a completely HORRIBLE person!!!! But it's true...
