Hey Kel, just a thought - do you tense up or something when the inlaws are around? Perhaps Jesse senses you're not comfortable/cool with them and the tension makes him cry?
Or are they unusually ugly?
River smiles at most people when they have a chat to him, it just differs, some he'll do that open mouth 'i'm delighted with you' smile, and others he does that shy smile at his feet - he even does that with us sometimes! It's super cute.

Rans is running River a bath in the big bath - it'll be the first time Rans has given him a bath like that! Actually, sounds like it's been running for awhile...might go make sure he knows what I mean...xo
