My children:
When I look at you I see many things. I see someone who has tried every corner in life and found your way to the place you want to be. You have fallen at times but always found your way back to the top. Many mistakes have been made but you have learned from them all. As time goes on more mistakes might be made, but I will always be there to help guide you and keep you from making more mistakes. I’m not here to tell you that I told you so, but here to tell you that I love you so. As a child you were so busy at play, now that you’ve grown, you’re so busy with not much time to play. The real world as you saw it as a child is not as you thought now that you’re no longer a child. For you, I can no longer carry you through, but I will always be by your side, and be your guide. Always remember what I have taught you about God; He will be the one to carry you through . I couldn’t be more proud of who you are. Always happy and taking everything life has to offer. You make the best out of everything. Anything that comes your way will be nothing but the best, I pray. I love you and always will. ( ITEM #S7 )

Baby: You are so precious. So tiny and so perfect. Cherished by all who love you and by God who created you. So innocent to the world around you. Your little hands reach out to be held close, your cry reaches out for comfort and your smile reaches out for a smile in return. So dependent on the one who returns your smile and who comforts you while holding you close. Not a word can be spoken of what you are thinking. Not a step can be taken to get you where you want to go. Still content with this all, you truly have it all. So tiny and so perfect. You are so precious to us all. Little one: You’re the little one who is full of life and has so much love to give. Always on the go even when there’s no place to go. The little smile you so proudly show with each new accomplishment; knowing the approval you will get from those who love you. You’re eyes look at the ones you love and you can see without a doubt their love for you never runs out. You are precious, Little one! You are the one that I can say, "I love You" to.
