don't worry! both of your children are normal
here's what i've learned:
1. only children take longer
2. girls learn faster
3. boys aren't usually potty trained until 3-3 1/2
4. some kids are busy when they need to go and will go on themselves b/c they don't want to get up
5. my son hated his "potty" so i had to get a special seat that fit on the toilet
6. some kids will do one and not the other for a while
7. sometimes they will go really well and then have stages
8. if they are alllllmost potty trained and you have a baby, they may regress as they want to be the baby
9. some children like to sit backwards but i discouraged my son from this as it gets EvERywHEre
10. if you have a boy, put cheerios in the toilet for them to aim at. cheaper than "tinkle targets"
11. accidents are normal even in older children but if it happens consistently when they are around 5 you may want to see a dr.
take care!
