Lost 45 pounds after pregnancy and now i've plateaued

Sammmish

Im 5'2 1/2, 26 and a first time mom. I lost 45 pounds using shakeology and the Slim in 6 dvds. Now im kinda stuck and losing motivation.
I could use more friends on here to keep me accountable (especially those of you with young children) and maybe some advice/ideas on mixing up my generally protein high diet.
