How do I approach this?

My friend is not present in the moment at all and it really affects us hanging out. I rarely hangout with her anymore because of this. She is non stop texting her boyfriend. It’s obsessive at this point. Just an example: today we went to the store. We got in the car and she said “hang on let me send a text” so she sent a text, he immediately texted back and she pulled halfway out of the drive way, stopped and said hang on she needs to reply. He immediately responds so once we got to the corner she again had to make us wait so she could respond. This whole time the baby is screaming in the car ( he’s 1 and doesn’t like the car to stop moving) every time she responds she has to go check his location so a 5 minutes drive turns into a 20 minute drive. It’s so annoying. We finally get to the store and she’s just staring at her phone while putting the baby in the stroller. They baby almost falls out, she catches him right before he hits the ground, puts him back in and says “can you please hold on I want to respond”. I just go into the store, I look around the ENTIRE store (it’s been like 20 minutes) and she is still standing at the front door texting. I go over and she is checking his location and I tell her I’m ready to go and she says “oh I haven’t even gotten to look around yet” I got so annoyed and told her she can just go back another time without me because I’m ready to leave. You can’t even have a conversation with her it’s like a brick wall and the baby is crying, climbing all over the stroller because he wants out. It’s so overwhelming. And then she gets frustrated that I didn’t want to go out to eat after. When we go eat out it’s like I’m eating alone. There’s no conversation and when there is, she stops mid sentence and gets distracted with her phone or she constantly asks me to repeat myself because she wasnt paying attention
