well, I have 2 and we all help each other. Even if it DID take me an extra second to get to my 6 month old while I run to the other end of the house or soemthing....my 2.5 year old will get to her first and say 'mama's coming Sarah, come with Joseph." Usually I get to the living room to find her dangling between her underarms and neck in his arms. And man does she look happy as a lark grinning ear to ear and so does he.
Boy I love my kiddos
If it's possible, having my second made me love everyone in my life a little more, and be even closer to my first born (which seriously I didn't think was ever possible).
There is something that happens to you after your second, the trying times, the toddler struggles, etc. Fortunately for me I was able to pull it together well enough that we never really had any 'bad' times. Being able to stick with my gentle parenting through the baby-blues for the second time, nursing 2 in bed, all of the sturggles...it really made me a stronger person. Sure I was a little sleep deprived sleeping with 2 kiddos, doing most of the night time parenting. But just the look on their little sleepy faces was enough to never ever want anyhting different.
I really really believe that for me, family bed is the absolute #1 important things in our life.
