hello ladies with or without kids.

Hi all
I have 4ry old whose summer vacation is from 3rd june and i havent enrolled him in his summer camp which is in his school for 1month.My hubby dint want him to go instead stay home and learn something but as i wished him to enjoy in his school beacuse of his teacher who told me to put him in school during holidays as he is bit lacking behing...anyways i wrote as i wanted to let u all now....but my question is after thining of not sending him to summer camp searched for some other outdoor activity like swimming classes or ect .

We r working on that but again if suppose he join then the swimming class is just for half hour butttt then what will he do for 2months as will be for the whole day with me..w E JUST DONT HAVE A SINGLE PERSON FOR TO CHAT OR COMMUNICATE AS MY HUSBAND DONT HAVE A SINGLE FRIEND IN HIS OFFICE .I want many many ideas frm u ladies as how to make him learn something that end of the vacation i can feel some change in my son(as more matured kid)as i am going to make him learn some words or anything related to it(the main thing is he is bit slaking behind with his speaking ability)so always concern about him, inspite of only we two person in his life to communicte with him in daily basis my husband dont talk to him often infact would say dont talk at all,he is in his own world always(but want me to make him super clever)as i try my best but if i dont get support frm husband then how will we do anything... His teacher even was concern about his mind being not steady at all in this one year ,just dont want to concentrate on anything he use to do in his class ,always just rome in the class and dont want to do any challenging works he was offered.pl ladies tell me how should i make him speak more and more(i try my bestt to speak with him)any tricks to make a pre-k kid more smart as he will join pre-k next year....any ideas pl pl let me know.

Waiting for everyones reply.
