Husband wants baby no2

My first born is only 5mo, and my hubby is requesting for baby no 2, I spoke to him but he don’t feel happy, saying we both should get another baby ASAP. I felt very pressure and unhappy, everytime he wants to have sex, I felt super irritated, I don’t know why. The feeling is horrible😭😭😭😭 can mummies out there share some thoughts with me, TIA #1stimemom #advicepls
