I need advice on how to get the spark back with my husband

We have been together for 4 years, married less than a year. we have an almost 2 year old daughter. he works about 35 hours a week and i work about 60. we try to take “us time” but it normally is just us going shopping or out to eat. we don’t exactly have fun anymore. we don’t talk like we used too. i guess i’m just wanting to know what other people have done to get that spark back in their relationship.
