Lucie that's our intention. My sister in law has nannied babies and supported new mums for a number of years and had amazing results in getting routines down within 6-8 weeks. Not always of course and each to their own, but we're going to try for sure.
There's a big possibility that I'll be taking a month and then going straight back to work due to uncertainty of DHs job and I can't be in a position of not getting sleep.
The routines she try's to go with start by everything other than initial sleeping happening in babies room to ensure that they become settled and used to their surroundings, all changes, feeds, play time etc happens in their room.
I know that recommendations are that baby cosleeps for 6 months but if I'm going back to work, there's no way that's going to work for me sadly. The way SIL has done it is that they cosleep for 2-4 weeks in a Moses basket with that being put in the cot after that time so they are still in their little bubble but getting used to having the cot bars around them. She has around a 75% success rate of babies sleeping in their own room 7pm-7am within 6-8 weeks.
As I say though, it may be total shit and not work for us, but I'm sure happy to give it a go.
