Congratulations baby girl. I feel our stories relate so much. I am also a mother of 1 year boy. The thing that I love the most. Similar to your case I also don’t think if I will conceive again. So when the baby came, I was s o delighted. I felt like I was living in the air. So I wanted the baby shower to be the best thing. I tried hard and to my perspective it was. According to me. A successful baby shower is the one that you are surrounded with the people that you love. When you have that much love and support around you. My baby is a boy. So my theme color was blue. However I had already told my family members before. That way the will come prepared. It is also not bad that you have decided to hide the gender. Telling the gender during the baby shower is going to be a surprise to them. And that is what will make the baby shower more interesting.
