I have a 3.5 year old and a 2 year old. My 2 year old son has been very well behaved and easier going than my daughter, up untill a few weeks ago. He is now getting more and more clingy and just wont leave me be for 5 minutes to even do dishes. He gets under me and I’m always tripping on him and hurting my back while leaning to do dishes. How can I stop this?
