Hi Gisele- I too struggle with this with my spirited LO. I really don't get a chance to do much work about the house and he's not the best independent player. So, I echo what pp has said- we try to do one outside activity a day. For example, my weeks are like this:
Monday: gymnastics class 45 mins
Tuesday: 9:30-11:00 community playgroup (mostly chasing after Nick and guiding him to play with the other kids, he's not had much experience as he's my only one and not in daycare).
Wednesday: Grandpa Bob day- he comes to visit and play. If he's not there, then visiting we go.
Thursday: library time 9:30-10:30
Friday: food shopping.
That way he gets out, has some time with other kids, gets some structured playtime, learns how to behave in stores. Then the PM nap 12:30-2:30 and play at home till DH comes home.
It has worked for us, but I still find myself trying to keep LO occupied safely and encouraging independent play. I've come to the conclusion that some LOs are just naturally more independent than others and mine needs to work at it a bit. I've got a friend whose LO is 14 mos and will play alone for 1.5 hours. I've NEVER had that. I'm lucky if he'll go 15 mins. But, I keep at it anyway.
