I have a toddler DS and I'm 20 weeks...so I think we virtually have everything for after birth and baby. Or am I kidding myself? Please help me make a list in case I'm missing anything!
I have a suitcase of mostly immaculate:
Sleepsuits, baby gros, vests, and clothes. We bought pretty neutral stuff for DS so happy to re-use if it's a girl.
Three gro bags
Two cellular blankets
Packs of un-used muslins
Cot and cot sheets - it's still being used by DS so I don't think I need to replace the mattress
Moses basket
Still have all the white noise/ lullaby toys clipped to the cot
Still have a baby bag of sudocreme, snuffle babe, snot sucker, cotton pads - all that kind of stuff. Will obviously replace any out of date medicine.
Box of breast pads
Still have the large knickers for comfort after birth and relatively unscathed!
Jug for warm water for first wee
Need to get:
New mattress for Moses basket
Pads for after birth
New breast pump
Aloe vera gel for my poor torn vagina 
Lavender oil for post-birth healing baths
Clary sage oil, raspberry leaf tea and evening primrose oil
Anything else?? I'm sure I read about tons of stuff for post-birth healing last time but can't remember much.
Nappies and wipes but DS is still in nappies so it's no big deal to pick up some newborn size. Hoping to give birth at home in a pool so have just a bikini top for that.
