Ok, P., this may sound crazy, but it worked for us. Both of my children slept through the night in their own beds without getting up until they were around 3 years old. My husband and I have very busy lives and I guess we get too busy at those ages. We received some great advice with our first child, took it, and it worked. Here it is...as your child gets older, they have the desire to know everything is ok. It's important for them to see their mommy and daddy together and spending time with just one another. It was suggested to us that we spend 5 minutes (to start with), every night, talking to each other. Yep, that's it, only us, not the tv, not doing dishes, just focusing on each other. We had to explain to our child that this was "Mommy Daddy time" and they could go play while we had "our time." At first our child played in the same room we were in, but we did not play, we were on the couch and they had toys. We had to explain how this was going to happen and they couldn't interrupt. The first couple times they thought it was fun to interrupt, but we just said, this is our time, you get to play. If everything is alright, enjoy your playtime. They grinned and went back to playing. My first child would get annoyed with us and eventually would just watch us talk to each other. We were amazed at the results. After our "time" we would continue with the nighttime routine, baths, story, bed. After about 4 "Daddy, Mommy times" there were no more out of bed interruptions. I can tell you, too, it was great to have my husbands undivided attention and he have mine. It not only reassures the kids, but you too. It's nice to remember that you came before the kids :). Our children seemed to need to know mommy and daddy were ok. If we didn't have our time, they would check to see if everything was ok while they were supposed to be asleep. Truly, now that they are in school, my husband and I need our "Daddy Mommy time" and the kids know to go do their thing while we talk. It's great. Just a suggestion. I hope you enjoy your new home and newest addition.
