Am slightly bemused as to why mothers who have never followed GF are so obsessed with others who do. Why do you you feel the need to scrutinise how others choose to parent-it's odd.
There are those of us who have followed the routines exactly and those who adapt, those who end up doing a mixture of both. I did it to the letter to begin with so can give Gina the credit for my contended babies 100 % as can countless others.
When appointments,coffee dates etc cropped up I made them sleep at said times by rocking pushchair or simply woke them for a cuddle or feed at the exact times just not in the house. After a while they can cope with it but I tried not to let it happen too much, people had to fit in round me. It wasn't a daily occurance just a couple of times a week, as soon as we got home we got back on track.
The mild inconvienience of being dictated to by a routine is outwighed big time with the results you enjoy (contented babies and a full nights sleep). Used to make me laugh at toddler groups as coming up for the lunchtime feed etc all the Gina mums used to stream out right on cue.
When I had my twins we were up all night for a long time. They had absolutely no concept of routine, I had no idea about how to deal with babies, my mother was miles away and couldn't give advice as it was 35 years after she had me. Friends I know were as clueless as me, followed advice from friends and family-it didn't work.
We were desperate, couldn't wait for weeks and months for a routine to drop out of the sky. You may be the type to run yourself into the ground waiting for said routine to manifest itself-I'm not, condemn me if you wish, I simply don't care.
They were cranky alll the time, I was resenting them as I was totally exhausted. I wasn't prepared to wait any longer. Gina was a total godsend-it worked big time !!!!!! It told me exactly what to do and I followed it to the letter. In a couple of weeks I had 2 contented baby and a contended mummy. I enjoyed them in the day insead of sobbing from exhaustion. Same story 15 months later with dd except I did it a lot earlier.
So some people do AP ,co sleeping(personally I would rather stick pins in my eyes),some make up their own routines, some use books. As has been said countless times we are alll different and can parent exactly how we choose as weall have different circumstances,babies and personalities. I am A SAHM it makes me happy, others work it makes them happy, we all do things diffrently,nobody has the right to judge.
