I have decided long ago that I must be strong if I were to be a mummy. We can't be worried about every teeny weeny things that happened or are going to happen to our children! Thing is, we ARE going to worry about them for the rest of our lives! So, we have to be selective in the things that we worry about.
I remembered once after my Os, I took up a sales promoter job in a Japanese department store. Everything went well until my boss' boss decided to make things difficult for me. I went home and casually told my dad about it and he also casually ask me to treat it as a form of training. I thought over it and told myself, yeah, I shall do what my dad says. And then life went on.
Had my dad ask me to quit, I think I would be quitting at every opportunity that I have now. As parents, even though we might have heartache seeing our kids suffer and all, but why not look at things in another perspective? Whatever doesn't kill you makes you stronger! But in order to not let your kids be quitters, you, as parents shouldn't quit first. Train yourself to be tougher on the inside. There are times when we must have heart of steel, but only for that critical moment. The rest of the time you can be as loving to your kids as you want to be.
So if you've got a child in a childcare recently and he/she cries all whole day, so be it. As long as the teachers are not mistreating him/her, let the pros do the work. Toughen yourself, toughen your kids. Actually kids are a lot more adaptive than us adults and you will be amazed that in no time at all, your child will be smiling again. :)
