Selfish to only BF no bottles at 6 weeks?

So this week my daughter is 6 weeks old. Before I had her my mother was pressuring me to give her a bottle as I’ll have trouble down the line. This week I went to my first baby and mother group and most of the ladies there said they express a bottle or 2 so their partners can feed the baby as they need “a break”. But all their partners were at work all day.

Am I selfish that I don’t want to do that. My husband changes her and washes her and all the rest between feeds when he’s home from work. Since I’m on MAT leave that this is my job for the next while and I’ll give her a bottle in a few months. But is this being selfish?
