I'd also go with your gut and how Eirwen is acting. Over the months, I've noticed that Asher often gets cranky and won't play with ANY toys if he has too many out. So I've kinda figured out a good amount for our room size. I also space them around the room, so no one area is too over-whelming. We have two small toy bins for smaller toys and then several large toys. We also have three things that always stay out (little tikes Garden, FP activity gym, and beanbag chair). In addition, I put out 2-3 large toys and one toy box of the smaller toys for him to pull out what he wants. Some days, he never even touches the toy box. If he happens to dump it all out and I see him getting frustrated, I just pick them up again. I rotate the toys every few days as I notice him getting bored.
Think you have a lot of toys now? Just wait until they all have their birthdays in a month! :lol: CRAZY!
