Thanks both.
To be honest, thinking about it now I'll be doing the childminder drop off with the toddler on some days so baby will have to be woken anyway! I know BW feels strongly that baby has to fit in with family life so I'm comfortable with that.
I know BW says she doesn't believe in
completely baby-led feeding on demand which is where the confusion was coming in - I breast fed on demand for three months with my first and it was horrendous, partly why we got ourselves into the problems we did! No routine, frazzled mum and baby etc. I won't be doing that again, hence wanting to get into a routine from a reasonable young age rather than waiting till four months.
The controlled crying wasn't because we wanted to drop night feeds or anything like that (he'd dropped them by then anyway), it was for literally not sleeping for more than 20 mins at a time and only going to sleep in our arms, not being able to self-soothe because we'd completely overridden it with what I now know to be accidental parenting. Life was hell on earth for a month
I know BW doesn't believe in it but controlled crying was truly a miracle - worked within one or two nights (so never longer than five minutes without soothing) and he was so much happier afterwards that genuinely I can't fault it. Obviously I'd rather not get to that point again so fingers crossed the BW routines and 4S's work this time around.
Thanks again!
