checking out Target maternity section today:

Their maternity stuff is in the bigger sizes section, their label is "in due time".

Clothing:
Bought my first maternity pants and maternity knickers today. Hard to know what sizes to take in the changeroom. I was the same size as usual in the pants but i tried on a top on in my usual size and it was way too small. I must be in denial about my top half! I have gone up from a D to a double D - i didn't think that was a huge change.

All my tops are so short now and now i see what maternity pants are like, with the stretchy band bit, really need to get long tops to hide all that band stuff of the maternity pants. Target didn't seem to have any adjustable pants, just ones with loose thick band waists, made out of t-shirt fabric. Also not much to choose from, hope to visit the ONE Baby Target in my state soon.

Does anyone have any tips on where to get "sleeping" maternity bras?
Or maternity bras with wider more comfy straps (like sports bras have).

I have bought ONE maternity bra that i got fitted for in a department store last week, in a flying visit when i was desperate and uncomfortable. I am so glad to have that and know that a fitting specialist fit me for it (so unlike when i choose them, this one actually fits).
