Take a good look at your kids... Are they TRULY ready to potty train?
Most boys are closer to 3 1/2 when they are... Most girls are OVER 2 closer to 2 1/2...
My hubby tried to get me to "train" our 2nd child before our 3rd was born (he was ALMOST 3) I have to say I almost lost it! There is no forcing that issue. lol Now with our 3rd (our 4th is due in a few weeks) I am not worrying about it AT ALL... Until he starts telling us he has to go... Then I will "train " him...
If the potty training is stressing you out then stop. Encourage them, but do not make it manditory...
Also... Mommy time is a must. AND MOMMY AND DADDY time is essential... You must grow the relationship with daddy and the kids will bloom because of it.
If you find yourself yelling... Put yourself on time out for a few seconds... STOP! close your eyes. Breathe thru your nose deeply 3 times and calm down. Fix the voice and try a new way. If you allow yourself to escelate the kids will go up in volume also.
Schedule!!!!! Make a schedule. The kids will adapt to it and will soon be telling YOU whats next on it. (Make lists of what you do daily, and weekly. Write them out and assign times) Make sure you are sticking to a STRICT bed time. Kids go to bed mommy can then sit down and relax a bit. Take a bubble bath, read a book, etc...
Does daddy maintain a cleaned up house? Or do you have to come home after daddys "play time" and clean up and cook, etc... Divide chores with him... He can do laundry and grocery shopping etc if he doesn't already...
Reprioritize what is truly important in your life and cut out the rest... Make time for walks with the kids and physical activity for yourself...
Good luck and get yourself some flowers!!! :-) I always feel better when there are flowers in the house...
