Only child

Hi all! Looking for some support-my husband and I have a beautiful 5 year old daughter and after 2 devastating pregnancy losses, she is going to be our one and only. However I have been struggling greatly with this and was wondering if there are any other mamas out there who only have one who would be willing to guide/offer advice/what to anticipate in being a parent of an only child. So many questions! Much love to you all 💜
