When we had first child we would let her come and get in bed with us when she would wake up in the middle of the night. Until I was big and pregnant with our second baby, the first would wiggly around and end of kicking me in the tummy. We decided that night that we could not do this anymore. I remember that first night of breaking her from coming into our room was hard and the next few nights were horrible. But once we did it, we didn't have that problem again.
Then one night when our second daughter was sick Donny was too tired to make her a bed on the floor, he said "just this once" and he laid her on his side of the bed. Yes, you guessed it, she throw up all over him and all over the bed. I was huge and pregnant with our third this time, and thought I was going to a... join the in the fun. Yucky!
So if the children are sick we make a bed for them on the floor by our bed or out in the hallway by the bathroom.
Since we had broken the first one from coming into our bed, the others really never did it. We enjoyed that until now with our 9th. Are we weak, older or just too tired?? I am not sure, but I do know that 20 years later I have another wiggly 3 year old coming and getting into bed with us and kicking me in the tummy again and I love it.
