DS (4.5) is an only child atm (DC2 due in March).
While he is getting better at playing by himself for short periods of time, I still find that he is constantly asking me for interaction - I don't mind it up to a point, but when he's out in the garden, even though I'm sat in living room keeping an eye out, I am still interuppted so many times. I always respond and often go out to look at what he is talking about (bugs etc) as I think its nice to share their enthusiasm but after a while it does get a bit wearing
Sometimes wish he could play by himself a bit more for longer periods and wondered if other parents with only children had this problem?
