Just too afraid of losing my baby 😔

Im a new mum (sahm), married to a great responsible husband. Our nb is now 9m and almost every night i cry while looking at my sleeping daughter thinking bout sudden death, sickness, or anything that can take her life. I love her so much and im just too afraid what if 1 day god take her life too soon?.. what if 1 day she will leave me for someone else? What if she meet with an accident due to my carelessness while crossing the road? And many more.. the feeling i have for my daughter is just too strong and i think ive never loved anyone this much.. i told my husband i dont think i want to have another baby cause i dont want my daughter to have lesser attention from us. Hes very understanding.. i lost my one and only beloved brother just 1 month before i gave birth and i am still grieving for him.. i miss him so much.. nothing can beat the feeling of losing my brother and the love for my child.. i pray to god every night for my daughter’s protection and the afterlife of my late brother.. thanks for reading mummies…
