Advice on friendship

I’m hoping for insight from ladies with young kids

I (24) do not have kids but have friends that are starting families. I come from a large family so I spend time with cousins or nieces and nephews often. I do have one friend that I’m struggling to maintain our friendship.

sometimes we would do something together and sometimes we took her daughter somewhere. I always interacted with her daughter. I never reprimanded her daughter as that is not my place. Instead I redirect to another activity or toy if she got into something. Things changed when she got pregnant. I felt like I was doing the wrong thing interacting with her daughter. When I would try to keep her busy by redirecting to a toy or activity, my friend would ask me to leave her be. We grew further apart. When I run into her, she is always rushing off and we don’t get to talk. I still talk to her kids before she leaves. She does have a few mom friends and is staying busy which I’m happy for. If I try to reach out over text, I get a short reply. I know postpartum is hard on top of being a stay at home mom. I still want to be there but I don’t know what I can do to maintain this relationship. I’m hoping other moms might have some insight!
