Toddler help!

I have a two year old, and terrible twos have been rough. Our son (I will call him O) prefers my husband who has to work later than me. O will not eat dinner without dad. O screams until dad gets home from when I pick him up after daycare (usually about 2 hours). What do I do? I feel like our son doesn’t even love me, he’s just stuck with me. Any suggestions would be amazing. I’m 39w4d pregnant with #2 and have just been crying because I feel like my son hates me.
