Daycare tips , dos and don’ts.

As the tittle , Well my kid 1.5 yo will start day care in April , I just want to know any tips or recommendations.

My wife is Japanese but she won’t be able to do the pick up or drop off all the time so mainly me (gaijin) picking up the baby.

By recommendations I mean tips like : Be part of every activity , be part of the gossip ladies or the mothers who does nothing but talk after the drop off or pick up , don’t offer your English lessons , do the exchange of gifts , and so on . .

Thank you in advance ;) .
