2 UNDER 2

Can someone tell me how it is having 2 kids under 2? I just had a baby last July and now I’m pregnant again and due in Dec. Also, is it normal to not feel as excited as you did with the first pregnancy? Will it change? Right now I feel like I don’t want to share my love with another baby.. 🤦🏽‍♀️ I don’t mean to sound selfish.. I feel like it will blow over.. I’m in the first trimester (7 weeks) & I feel blah.. nauseated, annoyed, tired.. etc I’m sure things will change in the second trimester (hopefully).
