How to deal with in laws after miscarriage

So we miscarried around the time of my sister in laws baby shower.. both hubby and myself didn’t go because of the emotions we were going through . We chose not to tell anyone about our pregnancy for the sake of miscarriage, Fast forward to now my husband has yet to see his Neice , his family are giving him a hard time because of not seeing her and honestly I don’t know how to help this situation other than telling them about the miscarriage. I also haven’t not told his in laws specifically because we have a strained relationship and the bad info or news seems to always be used against me . Any ideas on how to help ?
