I have a 16-month old and I understand exactly what you're talking about! Our dd is actually pretty well behaved but obviously they still get into things if they can get out of your sight....well, even within your sight. What we are currently doing is this:
She sleeps a bit late, usually until about 8 or so, and the other kids are usually up by then, fed, and have their chores done or at least started by the time she comes down to eat breakfast. So while she and I eat I am often able to go over math or english with my oldest daughter or do math with my youngest ds and get him started on anything else like handwriting,
ETC, or other workbooks. My oldest ds works pretty independently, and his dad has taken over the math with him (7th grade, yikes!) so I don't really have to review anything with him before he can get started. Once we've had our breakfast I can usually let her down to play....our dining room is where we do our book work and the 'playroom' is in our formal living room which is connected to the dining room......we just block off the doorway into the kitchen and family room, close the bathroom door, and she can play happily for about 30 minutes to an hour. I
did make sure I moved things I didn't want her getting into.....we had to move the markers, school books, colored pencils, etc. to a higher shelf......and now the lower shelf has coloring books and books she can look at. Once she starts to get fussy I will either give her a snack if it's time for that or have one of my oldest children play with her in her bedroom upstairs or take her outside for 30 minutes. Even my youngest at 7 can entertain her pretty well, but only in the same room as me.( He's still learning what it is okay and not okay to do with her.) Once she's had some playtime with someone and her snack, she will usually play some more in the playroom....coming into the dining room to sit on my lap or 'talk' to us occasionally.
soon we are finished with morning work, it's lunch time, then nap time. She sleeps anywhere from 2.5 to 3 hours each afternoon (most of the time) so we save our reading for then. This is when I am planning to do the reading from
Beyond....with my youngest ds this fall. We will get the 'right' side done in the mornings then the 'left' side in the afternoon. The biggest unknown is what our newest dd will do....we will have a newborn enter the house sometime in October so there is no telling what kind of changes we'll have to make!
I do have some things that I keep put away and only get out sometimes....we have some sorting bears, some tiny dinosaurs(not so tiny she could choke on them), Mr. Potato Head, puzzles, and we've tried crayons and paper...not quite ready to color yet, she'd rather chew on them.
I
do have her either sit on the floor near me to play with these things or in her high chair. None of them lasts too long, and we have to take a moment to get her started with something new quite often, but it helps keep the tantrums from boredom and inattention at bay. Occasionally I will turn on Sesame Street for her to watch while she has her snack...she likes to sit in her Bumbo and eat, and she absolutely ADORES Elmo.
I hope these things help some. It's kind of a 'learn as you go' kind of thing, even when you get suggestions, because each child is different. We have used the playpen some, and it worked if we kept at it, but anytime we get out of the habit/routine of it (like when we go to Nana's for a week and only use the playpen for naps and bedtime bc we only have one playpen) we have to re-train her. We have not used it since our vacation to GA a month ago....b/c I haven't felt like being persistent enough to do it. I do plan to start back up with it next week, expecting some crying, but we start with 10 minutes at a time a couple of times a day, then work more time in as she begins to get used to it. Usually after about a week, she's able to stay in the playpen for 30-45 minutes before asking to get out. I would say it is well worth a try for you....but then, if he climbs maybe not. I now have a second playpen I found at
Goodwill (YAY!) and will be able to be consistent now when we travel. I am expecting to use it sometimes when I am nursing the baby in the fall, as well as during some of our school times. Hope this helps, and I'll be checking back myself to see what others say....I can ALWAYS use more suggestions!
