Weird early pregnancy sign??

Ok this may be a little out there but... this past weekend my husband and I were at a bbq and a family friend's 4 year old son came up to talk to us and our of nowhere said "where's the baby?" And I asked "who's baby?" And he said "your baby! Where is she?" And my husband and I were so confused because I just missed my period 3 days ago but I haven't tested yet! Am I crazy to think maybe this means something?! My husband thinks its ridiculous lol
