Josie • Cosmetologist ✂ Nature lover🌲🌻 NLB♡ Matix Roy💙Sienna Colleen🌸 & baby due May 20th
Im 22 weeks just wanting everyones opinions on when its important to have all the big stuff? (Crib, carseat, ect) Im keeping in mind I have placenta previa meaning early labor is possible! I have nothing but a swing & a few outfits. Kinda feeling under prepared.
