Bad mom? ..

I feel like I barely see my son 😞 His father and I are co-parenting, 3 days each. My sons granny always asks to have him for a few nights, 4 max. She gets really upset if I say no and gets mad at my sons dad which causes him to message me, which makes me message her trying to explain myself which leads us to an argument.

Now, I feel like my son will prefer his granny more than me. When I had him, he was extremely crabby crying his eyes out. Screaming every now and then. He’s 4 months old. He naps for 20-30 minutes every 1 1/2 hours, sleeps most of the night. Sleeps from 9pm to 3am, falls asleep right after he eats & burps. Then sleeps again 4am-6am/7am. I don’t think it’s sleep regression. I think he generally doesn’t like me anymore 😞 he smiles at me yes.. but idk. I’m so sad over this. Here’s my boy.
