As
@catapillar said, low carb isn't necessary for T1. If you're getting decent figures, carry on. You might still be in honeymoon, so things might change as time goes by but you seem from previous posts to be proactive enough to figure out how to deal with that. Your kid has been T1 slightly longer than you, so I'm sure she'll keep you right if things go wrong - you're going to have a few good arguments with her in her teens when she says, "look, dad, I've been doing this longer than you, so...."!
This forum is very useful for a variety of reasons, but there's a definite tendency for it steering people towards low carb.
In my view, unnecessarily so in the case of T1s, and disturbingly so in the case of the Parents sub-forum which has a sticky post at the very top called "Type 1 and low carb" implying, incorrectly, that you as a parent of a T1 sprog must low carb them.
I always try to bear in mind that T1s are a minority - we're about 10% of the total T population and that's probably reflected in the general make up of the forum population.
Low carb is definitely a viable option for T2s, and many T1s benefit from it also.
What troubles me, though, is that many low carbers seem to think that it is the only option.
There have been some frankly insulting posts from low carbers suggesting that people like me who say that T1s can eat a reasonable amount of carbs are "irresponsible".
T2 input into these T1 matters is frequently less than helpful. Sure, T2s have to manage carbs in a certain way, but the biology of insulin/carbs
is different in T1s.
It worries me that newly dx'd T1s, who know very little about it at the start and who are looking for easy solutions, are in some instances being led down a path by posters on this site which leads them to view carbs as inherently evil, and insulin as an enemy. It's no wonder that so many T1s end up with eating disorders.
