My boy is getting so big

Nicholas turned 8 months old this Sunday March 27th, It is going by so fast. His new things are sleeping on his stomach that started this week. He is getting so strong, he is not crawling yet but he moves all over the place. He really learned how to use his walker this week. He makes me laugh all the time. He is always smiling and such a good baby. I'm 19 weeks pregnant already. I find out next week if its a boy or girl. I have been having alot of pelvic and hip pain with this pregnacy, not fun. I have gained 10lbs so far. Im so over being pregnant though. Getting pregnant back to back is not fun. I know once the baby comes it will be worth it.
