So far for me the worst things about being pregnant with a toddler is Changing poopy diapers with morning sickness and having her jump on my belly all the time. She doesn't understand that it hurts and makes me sick now. I love to have her cuddling with me but the jumping I can do without now. I can't even count the times I have almost thrown up today because she took a flying leap onto my belly. What are the worst things for you?
