As soon as my DD wakes up she starts asking to go to people's houses. Depends on the mood and whether I've told her no or not as to who's. If i've told her no she wants to go to nan and pas other wise she wants to go to her best little friend or her cousins. When I say no we're not going visiting she answers with "fine then mummy you can take me to the shops then". She has a play mate in her brother and they play really well together, we do swimming lessons tuesday morning, wed & thurs at childcare and friday is mothers group. And we always do something on the weekends as a family. So she has lots of socialisation and she still asks every single day and more than once.
Sounds like it's just another thing they do. I'm hoping anyway because I really can't fit anything else in, LOL!!
