Should we go for another kid??

L

I have a daughter who is now 2 years of age and my S.O wants to have another kid but I’m not sure I want that. I am worried that it will affect my daughter massively because her whole life she has had 100% of our attention and with another kid around she wouldn’t get that. Also my brothers and I always fought since the I began walking and I really do not want fighting in my house. I have always liked the idea of one kid as it means less to worry about and also easier on the wallet but my daughter has recently been bugging me about when she will get a baby sister or brother. So if anyone’s got any benefits of having one child or two children please comment. Also if any one has been in this situation before comment what you did and if you regret doing it or your happy you did it.
