Mummies please help..

My lb is now 20wks and I have been weaning for 3wks.

He has rice for brekkie and veg puree for lunch (Peas,brocolli,sweet potato, carrot, butternut squash)

I don't know whether to be worried about his Nappies, they can be quite snotty and are very smelly.

I'm hoping he is just getting used to the food as don't want to take it away, or he is badly teething as he is a happy but hungry baby.
