My daughters bday is next Month. She will be two. Before I was prego I was excited and looked forward to her bday party. Now I'm just tired and feel like it's going to be crazy. I'm Mexican so we usually have big parties. I wanted to announce that we are pregnant at her party at the end but I'm so not in a mood to host her birthday party. I feel really bad cause we had bought some decor. And I feel like I'm putting her to the side😟😢😧. I really don't know what to do. Should I throw her a party or just buy her clothes /zoo?
