Hi Eunice,
I am a mommy of 3 gals and fully understand what you are going through. Have faced the same situation as you before and stressed about it too.
1. I am shocked that your gal only wore her shorts when there is clean panties in her bag. But then, from my experience, I know that the children are usually the ones who dress themselves, not the teachers, after their bath time. So maybe you will have to 'teach' your girl that she will need to wear her panties under her shorts? Just remind her and also show her where you pack her panties and clothes. No point telling the teachers cos they will tell you, :"I one person got to look after so many kids, very hard for me to monitor all." Been there, heard that all before.
2. My 2 elder girls and attended a total of 4 different CC's. And so far, none of the CC's they attended have ever marked any of their shoes. I am shocked that they will need to do so. Since the childrens are already put in a cubby hole with their names. There is no need to mark the shoes then. Fully understand your frustration here.
3. My gals too have lost many hairclips, hair bands, etc. Whether its at the CC, Enrichment classes or elsewhere. So now I don't buy them any expensive clips. Any cheap ones will do. If I do get expensive clips, I keep those in my drawer and let them use only on weekends.
4. This is actually quite common. All 4 CC's my gals been to... the matress covers all have their names written in black marker right smack in the centre.
5. Experienced this before too. Actually I'm not too bothered by this as it makes sure that the teachers will make the correct amount for my gals. This is especially as they make the milk for all the toddlers at 1-shot. SO sometimes there can be many similar bottles and easy for the teacher to get mixed up.
At the end of the day, after much frustrations and stress too... my main concern is whether the teachers treat my girl well. Make sure her needs are met, she is well cared for and most importantly that she is happy at the CC. Other then that, I cna live with the minor irritants. hahahah...
