So so hard, i hope your sister is ok and is up and about ASAP.

I completely understand bubs need cuddles and i agree at this young age they do need it but if possible i would try and find the middle ground, maybe cuddle to settle but then pop into bed and pat or something once asleep, or if need be cuddle as much as you like at the start but try and draw out the need towards the end.

MIL has always had a habit of not handing grandchildren over once asleep, she just holds them and holds them, after i had been in hospital for surgery it took me forever to get DD1 back to normal (i don't do controlled crying or anything but she WAS the kind of baby who would sook for say a min and then put herself off to sleep) and this didn't help my recovery at all.

GL, do what you feel is right i'm sure in the long run thats all your sister would want and thats why she is leaving bub with you.
