My oldest two (boys) are 15 months, 5 days apart...and it was planned that way. It was hard, but we survived. The gap between boy#2, and my girl is 23.5 months. So, I had 3 kids, ages 3 and under.
My husband lost a fantastic job due to the economy when our kids were 5, 4, & 2. We both went back to school FT. It was a nightmare, for the most part. We couldn't even entertain the thought of having our 4th child at that time. I graduated nursing school, and he graduated electrical lineman school, and we both got jobs. It took awhile to feel established again.
When the kids were 5, 7, & 8 we started ttc. It took longer than ever expected, and we ended up with a mmc in March 2012. After an incredibly broken heart, we kept ttc. After about 18 more months, we stopped trying, and just didn't prevent. Three more cycles later....bfp!! That brings us to today, and our kids are now 7.5, 9.5, and almost 11. We are thrilled!!! We have 3 little babysitters! I'm 35 now, will be 36 when this one is born. So, this is our fourth and final!! It will feel great to feel complete!
