I think that knowing when to potty train and finding the right potty - http://motherbabychild.blogspot.com/2013/01/potty-training-2-year-old-toddler-boy.html - is harder than Potty Training a toddler boy. If the average potty training age is 18 months to 3 years, then why are so many of the potty chairs so low and small. Do they need to squish our baby's up like that? BabyBjorn pottys have good space and nice guards for boys, which one did you choose? Have any tips for other moms?
