My 3 month's old keep crying on other people

[kels1992]

Hi I have a 3 month's old baby boy I am feeling upset that he keeps crying on other people. He is fine with me and his dad but others he's not. I have tried everything when his grandparents come over he screams the house down. Is there anyone can help me please thank you x

Mine was the same only just started to get over this at around 7/8 months!! Just comes with time and then trusting them I think but it was upsetting
