BTW, WISE scheduled feedings will never result in Failure to Thrive.
All of my babies started at approximately every 2 hours from birth. I didn't intentionally do this, that is just about how often they needed to eat. They gradually spaced out their feedings more and more. I kept them LOOSELY on a schedule, because it was easier for all of us.
The need to eat, and the need to SUCK, are two separate and independent needs in infants. So I gave them a pacifier in between nursing them. I'd rather give them a pacifier that I can throw away when the need to suck ends, before it becomes a habit for other reasons, instead of having them suck a thumb until they are in school (one of my daughters sucked her fingers and had deep bleeding cuts in them from her top teeth - she was born when her brother was 11 months old, and he had just been weaned from the pacifier, so he thought it was bad for her and kept taking it away).
Sometime around three months, they started sleeping through the night. But during the daytime, they pretty much stayed on a schedule of every three hours as long as I was exclusively nursing them. I did not try to push them out from what they needed.
All of them were healthy (even Alex, born with Crohn's, stayed healthy until he was 7 years old), rarely got sick, were contented and mostly easy babies (except the one with Fetal Drug Effect from my having surgery while pregnant with her - necessary to save her life).
The only time it causes trouble is if you try to regimen them outside of their actual needs - when you are forcing a newborn onto a 3 or 4 hour schedule, for example.
The key to healthy feeding is NOT in nursing them every time they fuss (I know people who do), nor is it forcing them onto YOUR schedule. Either one can result in eating disorders and avoidable behavioral problems (too little control on the part of the parent is just as damaging as too much, and indeed, abusive adults as often come from homes with too LITTLE parental control as from too much). The trick is listening to the child, and meeting their actual needs in a healthy way. It is the JOB of the parent to determine needs, and provide appropriate structure and routine in the life of the child, and feeding is one of those areas where appropriate structure is required.
BB, one thing you will find as you get further and further into parenthood. Many things you are told by others end up not being true FOR YOU. Worked for them, doesn't work for you. You'll form strong opinions, reach conclusions from the experiences of others, and start out with a plan based on those conclusions from what you've learned to that point. But parenthood often changes that - we definitely morph as we go into someone we did not exactly expect to be, mostly I think, because our children turn out to be someone we did not exactly expect THEM to be!
What works for your first won't necessarily work for the rest, also. One kid may DEMAND that you schedule them, another may refuse to be scheduled. Kids are like that, each individual, each with different needs.
I didn't expect to be where I am now, researching things I never wanted to do. I never wanted to deal with cloth diapers - they seem no more environmentally friendly nor cost effective than disposables, they are just a heckuva lot more work, and since I had three in diapers more than once, the work load won out! It would again (since I am no less pulled in twenty directions now than I was with seven kids under the age of 11), were it not for the fact that I know this child is different than my other children. I feel it in my bones with a deep certainty - a calm feeling that this time I will have to rewrite my own rules for parenting because what worked with the other seven isn't going to work with this one.
