Alright, let's be 100% honest.
Legal Aid obviously didn't reject your case because you earn too much money, so reason would suggest Legal Aid rejected your case because your case simply doesn't have any merit.
You then came here asking what to do next, and I told you exactly what to do next - either get a lawyer, represent yourself, or negotiate.
Your response, then, was basically just a campaigning speech, as though trying to get me on board with your cause.
Please understand that this forum is not a support network. Nobody here is going to nod along while you bemoan your ex, bleating about how hard done by you and your kids are. If all you want is someone to make you feel good and tell you what you want to hear, then head over to Facebook.
Here, you're going to be told the reality of how the facts that you provide would be considered against the provisions of the Family Law Act, and let me tell you, reality hardly ever aligns with expectations when it comes to this field of law.
I've read the facts about your matter a dozen times, and still, after many, many posts and threads, nothing new or compelling has been brought to the table that would drive me to say anything different to what I have said before. In fact, all it's ever really done is cause me concern that you lack insight about the reality and effect of your situation.
So, let's round up the reality of your situation here.
You've already agreed to 50/50 for two of the three kids, which, in the Court's view, is the same as saying you agree 50/50 is in the best interests of the children. In the absence of any significant change in circumstances since you made that agreement, you're going to find it very difficult to persuade the Court you made a mistake and 50/50 is, in fact, not in their best interests.
That, in turn, lays a pseudo precedent for future care arrangements for the two-year-old, as well, because the Court is going to be reluctant to put the kids on different care schedules. If you have agreed 50/50 is fine for two, then you've also agreed by proxy that it's fine for the third, as well.
On top of all of that, you have not given any persuasive reason for 50/50 not being appropriate for all three kids.
Your complaints about the psychologist are confusing, at best. Dad seems to be seeking out treatment for the challenges the kids are experiencing. You, on the other hand, seem to think they don't need a psychologist, even though they're apparently complaining to you about how they're fearful of their dad. Isn't a psychologist the first expert you should be enlisting to help validate or, better yet, resolve those complaints?
The breastfeeding thing is still not the persuasive evidence you obviously want it to be, either. If you were exclusively breastfeeding an eight-week-old infant, you'd have a valid case, but your child is two years old, not two months old. His or Her Honour isn't going to care about your full breasts or your emotional breastfeeding journey, because your child. Is. Two. Years. Old. Like it or not, agree or not, the harsh reality is that she doesn't need to be breastfed anymore. If you want to keep breastfeeding, that's fantastic, but the Court is not going to accept that as a good enough reason to hinder a two-year-old's time with her dad.
Now, Legal Aid doesn't think your case has merit. I don't think your case has merit. If you want to carry on with proceedings as a self-represented litigant or by hiring a lawyer to the tune of $20,000, to try and end the 50/50 care arrangement that you agreed to, that's your prerogative, but any sensible person would see the best outcome is at least trying to negotiate consent orders.
Except for sheet stubbornness, you have absolutely no reason not to try and negotiate. Who knows? Maybe dad will even agree to less time with the youngest, because I can't imagine he's too thrilled about having to take you to Court, either.
By the way, yes, I have breastfed, and no, that has at no time made me any more of a parent to my daughter than her father is.
