As a parenting teacher...I'd like to say that kids need to learn to play by themselves some of the time. And not on technology (Just had to toss this in).
We tend to "over parent" our kids today. Give him crackers/toys and an excersaucer and play with your daughter for 10 or 15 minutes. I am not against a playpen. Me and ALL of my friends were put in one a few times throughout a day way back when.
Take her to a local library that has a kids section and let her play with kids w/ you in view one day a week.
With that being said, your son should be put down at 8 months. He is not learning to nap himself. He is expecting your undivided attention in this moment, too. It's okay if he cries for 20 minutes 3 or 4 days in a row until he could do it on his own. Put him down when he is awake and not overtired. My sensory child would only sleep in a swing !
Discipline means "To Teach"---and it is what a child craves. So, if they both want your undivided attention all the time and he will not nap on his own...Then discipline needs to take place. It is easier said than done.
Let me give you a sad example: We have two Moms in town who have daughters. I have watched the girls grow up. Both of the Moms think their kids are gold and have always played with them, given them almost anything they have wanted, complimented them all the time...Think they are queens. The words "no" or "wait" weren't really in their vocab. Even now, the kids and the 2 Moms wear expensive clothes, boots...have the BEST. Well...I was at so and so's house the other day and guess what?
These two girl (age 12) had pics of themselves on snapchat---They were in their bras....AT 12 ! Of course, why not? They have always gotten tons of attention...And now they are "CRAVING" the discipline they never got.
And this is how they are doing it.
This is a sneak peek into what a "DOORMAT" parent is. The tweens seen
nothing wrong with it. The boys get the photos and nobody at home sees this??? Sadly, all of the Moms of the boys have seen these pictures. How embarrassing for the parents of these 2 girls. But, the girls still do not do anything wrong !!
I use this example when I speak to parents. It clicks...after it is told this way.
Every child will not do this!!! I do not want to give you this impression. But, this is the risk parents take if kids learn to manipulate at a very, very young age partnered w/out discipline.
When you are folding laundry and she wants you to play her way, she has to learn to wait until you are done.
Have a daily routine...Breakfast, outside play, library playtime, lunch (Let her help prepare sandwiches), Mom folds laundry and cleans while baby naps and you read and play with her the second half of the nap. When baby wakes up, she could give him a snack...play with him together...She could "read" a book to him.
While you make dinner, pull out a "dinner box of toys"...I used to do this. It works like a gem until one gives in and does not save them for dinner preparation.
If you feel anxious, they will feel it, too. Have a routine! You received some great replies !!
