Where is our relationship going?

My wife and I have been together for 15 years (married for 5 years). We have been together since highschool and we are now in our early 30's. We have one newborn child together. We used to do things together a lot before having our new born child. However, since she has been pregnant we have not really had ual because I thought I had ED. Apparently the doctors think I'm ok but I don't think I am the same as I used to be, meaning it takes me a while to really get . I feel I still love her but i'm wondering if she feels the same way towards me. She spends a lot of her time with her mom and her sister. A typical week consist of work, come home, pick up the baby and we eat dinner together and talk for a total of one hour before we go to bed around 10:30pm. A weekend typically consist of cleaning the house, chores, & she spends time with her mom. Her mom visits on average about 3 days a week. I love my in laws but sometimes I wish her mom can have a life of her own. We bicker a little and sometimes it turns into an argument. I feel we are drifting apart because we don't spend time with each other. I love the outdoors and I love being active. I'm always proposing stuff to do together but she doesn't do the same. I feel I am always initaiting stuff to do but she seems to pay attention to the baby more than me. And if we can plan anything because her mom usually gets to her before me when planning to do something. I'm upset that we haven't had ual in a while and I'm upset that she spends time with her mom, sister & her family more than me. So work, her family (mainly her mom), my daughter and all her "errands" occupy her time and barely with me. We've been together for a long time and obviously I'm upset, sad & I care about our relationship. Do you all think she is driffing apart from me? I know I should take action but I just want to get y'alls view on her feelings based on what I described.
