two moms catering

Need help in handling rambunctious kids?
I’m in a relationship with a single mother of three. They have been alone for several years and well the kids rule the house. Two girls are 10 and 8 and help mom when they have to, but both talk back and manipulate mom to get what ever they want. And then there is a 4 yr old boy who is off the chart, demands a lot of attention usually he will ask for what ever comes to his mind and if there is no immediate response within seconds will start screaming and yelling till he gets catered to. My experience is with one daughter who is 13 and very well behaved with full manners. I know that this road will be long and trying so I am asking for insightful experience or thoughtful advice.
If you really like this woman, then I say go for it and try hard! You have to weight the pros and cons IMO. You already have a well trained daughter, so it’s not like you “need” the Daddy feeling.
It’s EASY to say that things won’t change until the mother puts her foot down, but as you stated the kids are manipulative and RUDE. I wish I could talk back to my mother, I’d have to fly from Florida to Cali to pick up my lips off the floor!
Someone stated that you should get to know the kid’s likes and dislikes, that’s a good start. If you have any type of custody/visitation of your daughter, include her too. Maybe her good behavior will rub off!!
My mom and dad have 3 daughters, after they split my dad started dating a woman with 3 daughters and a son. They were the COMPLETE opposite of us. I didn’t know WHAT my dad was thinking. But after FORCING us to mingle with them, their mom said we were starting to rub off on her kids. They were using “Please” & “Thank You” They didn’t talk back, as much, etc…
Everyone’s different though! So whatever you decide to do – GOOD LUCK
