Feeling like a bad mom

Today I woke up a little later than usual because my almost 5 month old son went to bed later last night. Which I’m thankful for. But the whole day I’ve been feeling so sick with a headache, nausea, and ended up throwing up. I took a nap with him to see if it would go away but it didn’t. Tried drinking more water. But I felt like I just couldn’t give him my all today and that it was just blah. That he just laid there while I sat there. My husband gets home really late so help until then. I just feel really bad that I just didn’t do more for him today. I also feel terrible because when he lays there on his play mat I’m on my phone or something. Instead of engaging with him or speaking to him. I hate myself for that. I am a stay at home mom and I feel like I’m a shitty one at that. Whereas daycare there are other babies, caregivers, etc. I just feel like he lives the same day everyday but today was just worse since I didn’t feel well at all. The mom guilt is so real and I want my baby boy to have better...
