An Unusual Question?

Before we even get started I promise to post a post with more substance in it soon but for now just humor me!

I am figuring someone out there can help me and I sure would appreciate it! I am kind of a "think ahead" nut. I shouldn't but it helps me to prepare and to adjust when I think ahead. I also like to have things somewhat ready for when the girls come home. I know we will have a few things we will need to get done but I just want to be as ready for them as possible and since I am less busy now than I will be once they are here- now is the time!

The clothes Sarah has grown out of will fit Emma perfectly but I am not sure about Ellie and I want to have things here for her that will hopefully fit her. I should have asked the question "DO the girls where the same size clothes?" It is so hard to get an accurate perception with a photo. By looking at the pictures I would think the girls were Sarah's size but they aren't. Sarah is 4 inches taller than Emma and 6 inches taller than Ellie.

My hubby just isn't cutting it as far as talking about girls sizes. He tries but he really isn't helpful and since he hates shopping he really has no clue. So ladies I need you!

Sarah is 4ft 6in and 69 lbs

Emma is 4ft 2in and 54 lbs

Ellie is 4ft and 61 lbs

I am going off the sizes at GAP KIDS. Sarah is on the low end of a large (tops and bottoms)but it fits really good with a little extra room to grow.

By the looks of the chart Emma is a 7 on the bottom and I am thinking a medium on top. There will be a little extra room and I am sure by fall she will be an 8- yippee, I have plenty of that size!

Ellie should be a size 7, too but she is stockier, so what do I do? Do I go up a size so it fits her tummy or will this size fit? Maybe I should do an 8 to make sure? I want her to be comfortable and have some cute things. I have no accurate perception of her size? For Emma I can just think of Sarah when we first brought her home. I think Ellie will fit into a medium which is 65 to 72 lbs but I think her chest may be broader so do I go to a large in some shirts that fit tighter? Large is for 73 to 81, she is only 61 lbs?

Is you child, your niece, or your neighbor have a broader shape? What do you or they do?

Again I apologize for this post- obviously I can't ask my friends! They are excited to retire! This is not something they want to chat about! That is why I appreciate you all so much!!
