Age gap in kids?!

Hi Glow Girls my husband and I have been ttc for about 4 years, my daughter will turn 6 this year and it doesn't look ill be having a baby this year, my worry is my daughter getting older and won't have anything in common with the bby in the future because of the age gap or won't want anything to do with the bby because of it. Have any of you mommys have had kids with these major age gaps and has it affected in any way? Or is it just fine? Any opinions of what you all think? Thank you 😊
