Anyone else struggle to parent while pregnant?

Anyone else pregnant with a toddler at home and sometimes feel like a bad mom because you’re so tired? I’m 29 weeks and my 20 month old is so active and adventurous that I just can’t keep up. I find myself getting so frustrated and wishing I did more with him, all while forcing myself to do more and end up sore and unable to sleep at night. This pregnancy is so much harder than the first one. I’m short tempered with my husband and brush off my pre-teen SD when she wants to do stuff. I don’t like who I am when I’m pregnant. Can anyone else relate?
