Hmmmm kimiko,
I also think that going back to Yr mum's pl is of cos the best solution to enable u to have rest n etc. But will u as a result also keep worrying abt how Yr hubby n mil will think n what will happen after u go back to Yr mil house?
I feel that u shd not neglect how Yr hubby will feel. Though he didn't bear the bb but I'm sure he is as excited as u are and would want to form some form of bonding w bb. Also, I rem u mentioned Yr mil actually wasn't that hard to get along right? So maybe like one of mummies say, the idea hasn't sink into her what's Yr needs yet...
I dunno how's Yr actual situation but I think prob u, mil n hubby can sit down n tok abt each's concern. Strangers in the house, night care, CL, bonding etc.... N see if can come up w solution bah.... I still think no point straining relationship unless really can't be help, I'm sure the more each of u mind is exactly care for each other too. Do highlight Yr worries abt Yr health n not wanting to wear down Yr health so that u can give her more grandchildren too n u dun wanna tired her out too. As for man Yue, u can say I traditional... But I think it's impt to respect elders thinking as in it's her 内孙, that she would want to hold it at her place, it shows she's proud of her grandchild too. U can always hold over two days for two sides relatives or hold at a neutral place outside to save cleaning the house. As for Yr parents, I'm sure they will understand....
Dun let this thing wear u down emotionally.... There's still months to go to get things settled, just my two cents worth....
