Is this normal

My husband and i have two kids, toddler and baby. I am 32. My husband is not very helpful with the kids but for some reason I am still really really wishing to have another baby. I love being a mom so much and i feel very sad when i look at my almost 2 yr old and think this is the last baby stage i get to experience. I know i sound crazy :(. I cant stop thinking about adding to our family. I do all the baby work and work full time from home. I feel like i have the energy for one more. Has anyone gone through this ?

Ps husband doesnt really want one. He has mentioned adding one but then goes back. I cant stop thinking about another baby.
