I been thinking so much how I'm gonna handle three kids Lol especially with baby three and my 8 month old who will be a year and 3 months when baby 3 comes. my oldest will be almost 6 when the baby comes and he is big help so that nice. but with hubby working I'm a stay at home mom and I feel going from 2 kids to 3 with 2 being close in age I feel like its gonna be hard to transition! any tips? I know I still have awhile to go but this is the one think that's kinda scarring me Lol.
