Coping :(

I have a two year old daughter and am expecting my second baby next May. I'm a little worried that I'm not going to be able to cope with two children. My husband can be pretty useless at times. We are both full time working parents. On his days off he would rather go watch the football or play on his games console then look after his daughter. Where as I would rather spend time with my daughter. I'm worried that  going to have to look after two children on my own!
