NEW BABY!!! Aha.... now it all makes perfect sense.
A new baby in the house can definitely be the reason behind all that you are going through.
My DD was 3 when DS was born. I tried, and meant well, but ended up not giving her enough of my time and attention, and I am going to try to do better by both of them this time this winter when #3 is due... but I know realistically, it's never easy for kids to go from most of my attention, to a lot less because of the demands of a new baby.
Mine are both (and we're talking nearly 3 and just turned 6!) acting like they want to nurse again, and both were weaned at 2 1/2 when I got pg with the next (couldn't get past the heebies)... and I, who never used pacifiers before, am actually considering buying one for each child, because the baby isn't even here yet, and they really want to go back to being babies in some symbolic way, and I just can't keep from having my skin crawl if I try to let them pretend to nurse (I am dried up and all).
So here I am, considering play pacifiers even though I don't believe in them generally, to help with a newly emerging need to role-play babydom, for my older kids.
And I am also remembering that right about the time they get walking, EC gets to be a giant headache unless you are in a country where children squatting and pooing on the street is acceptable, which we aren't.
So now, even though I want to EC again this time, part of me has become more aware that, first off, cloth diapers are no crime, and secondly, we can't be perfect, but if we can be sane and calm as mothers, even if we have to diaper to do it or get pacifiers to help older children act out a need to return to symbolic babyhood (and yes, they get TONS of love and cuddles so it's not a lack of genuine mothering!)... maybe that's ok?
Maybe it's ok to do whatever you need to, to keep your own family as happy as possible, even if it means abandoning ideals of some system that we all believe in?
That's the biggest lesson I am learning, at 37, as a mother of soon to be 3. That being able to have a happy, comfortable, harmonious home and family, is more important than successfully adopting every possible advantage in natural parenting from other cultures, when it's an uphill learning curve, or for whatever reason, it's not making anyone happy in your own home at the moment.
If you need validation, to give yourself a break, give her a break, and toss EC right out the window if you have to, to be a happy mama and have a happy child, I say do it.
My first child wasn't EC'd, was totally cloth diapered, and she turned out fine. It didn't harm her in the slightest.
EC is thrilling, and I am tempted to do it again this time, but also wary of the "difficult period" and wondering, since I can't let them go barebottomed in public and squat wherever they want on public streets, whether it's really worth it, to attempt to adapt it to my own culture, when we hit that hurdle. I guess I will find out when I get there, but part of me agrees with those who just say hey, cloth diapers aren't the end of the world. My friend, who does cloth but not EC, doesn't deal with any of this stress, though she does deal, calmly, with a lot of diapers AND a toddler who is now being just as annoying, screaming and writhing and resisting, when having his diaper changed.
who can tell, really, how it's going to be? All we know is, at a certain age, not easy.
Good luck finding a happy solution. You don't have to prove anything to anyone else, don't have to become an acolyte of EC... life is about having a choice, changing your mind, and doing what works out best for you and yours, in the moment.
I'm going to be trying to find that balance, too.
