YW only for a morning or afternoon with my SIL or mum, which is irregular but something he's used to, enjoys and hasn't had any effects before. He spent Sunday afternoon with SIL but it didn't start till Wednesday. Wednesday morning he was with my mum 10-12ish while I had my interview, then 12-4 Friday afternoon. The longest we've ever been apart was mid-afternoon to mid morning but that was back before Christmas. He's not sleeping well enough at the moment, especially as he's more unsettled in his travel cot, to be left over night and I always leave for work after bed time so he doesn't know I'm not there iyswim. 'Tis a mystery, hopefully one with a nice quick resolution 
Soph skype for sure. That's a huge thing for her to be facing up to, both the decline of the relationship and her own sexuality
