im sorry for all the kindy posts recently!
but my DS is 3 and i am currently trialing a new kindy as well as his old one as i am not sure im happy with program,,
anyway today at new kindy a few issues didnt sit well with me..
firstly when i dropped him this morning i stayed and watched him in playground where i admit he is a little ruff (as boys can be) but the older class play together and a group of 3 boys obviously close run around together and he tried to be part of the group,but they pushed and shoved him saying go away. he took this as fun luckily an wasnt hurt just thought was a game.. i let this go even though it annoyed me
then he must have grabbed a toy from another boy and when i turned around he started crying only to discover 2 boys were hitting him because of it. a teacher pulled them up he was fine... this also annoyed me. but he is good at standing his own ground but do i want him associating with so much ruff behavior?
I had a general chat with his group leader who seems lovely and she mentioned him wetting his pants and that she was concerned because he doesn't come and tell them and she doesnt want him in soiled pants obviously. this is no surprise to me, it happens he is toilet training..
then when i picked him up today (and although he is not very articulate) he said he was crying and when i asked him what happened he said his teachers angry and cross because he wet his pants and they told him its disgusting! now is it just me.. but should i be concerned.
oh i just wish i could watch from a distance to see how some staff really interact with children
now i dont know what to think.. could he be exaggerating? but i have never taught him the word "disgusting"..
thank you for reading this... but now im concerned.. do i mention something?.. or how can i without them now judging me or my son? will they continue to behave like this? is my gut telling me to leave?.. i swear i have looked at every kindy and the only one i like has a huge waiting list... but the more i think about this new kindy the more i still feel comfortable with his other one... (added bonus about new one is program seems more exciting they include food and its almost half the price!) sorry this is just doing my head in! love to hear opinions
thanks again for reading my mumble jumble!
