Is this normal ?

I just had my first baby girl a month ago. I’m so in love with her and I feel what the heck took me so long to have a baby. I’m only 28 but in my culture we start early with babies. I know everything happens at it’s time and that she came at a perfect time. I am already looking forward to bringing her a sibling.. is this normal lol? I’ve felt this way even closer to my due date, I felt sad not being pregnant anymore.
