Changing hours

[playfelt]

At 18 months I would be using something confined for time out if that is how you discipline such as a play yard or high chair, etc. that eliminates the getting up out of time out since they are there till you come back for them. Their attention span is so short the getting up is partly because he has forgotten why he sat down in the first place.

It also sound like the two of them are bonding in a sibling way and ganging up on you - so not fun. If mom is pregnant she is probably being either really strict cause it annoys her or really lax cause she just can't be bothered and he is testing you to see where you stand on it all. Sometimes just sitting back and watching the play will show you things like toys that need to be put up for awhile, or how a change in arrangement of furniture might help - ex toys all around the edge of a room and open space in the middle encourages making a dumping mess and running as compared to putting a couch across the middle to section the room - blocks and cars stay on one side and books and puzzles on the other.
