My FIL is a major Douche if that counts for anything. He is a VP for the corp. he works for and loves showing off how much money he has. My wife and I have been married for 2 years together for 6. I have never been in his house or had a actual conversation with the man. His idea of show his love to my stepdaughters is to buy them anything and everything they want. My stepdaughters are 12 and 8 they both have Ipads, Ipod Touchs, Iphones, LapTops, Flat Screen TVs, Wii's, XBox 360's. Thats is one for each of them they dont share. This is just an example of the stuff he buys them. He spends an average of $1500 a piece for Christmas. It pisses me off and my wife wont tell him to stop. I understand he wants to by them some nice things but he goes way to far and they are going to expect this kind of stuff for the rest of their lives. My wife doesnt see anything wrong with it
If your wife turned out fine (which I assume you feel she has since you married her) I would assume your stepdaughters will turn out fine as well. I wouldn't worry too much about it.
