Family unsupportive of pregnancy

Does anyone else have unsupportive family? This will be my 3rd baby. They were already upset when I had my second and I’m dreading announcing my third because of them. Their reason is simply because they don’t want me to have more not because we can’t provide for more. They think I can’t give my first enough attention even though I’m a stay at home mom. All I do all day is give my children attention. (They also had multiple children themselves?) I’m confused why they are so against it and sad I can’t happily announce to them. If anyone has any advice to deal with this or in a similar situation let me know! I feel pretty alone right now.

Also to add my husband is super excited! He’s hoping for another girl 💗
