RobinG (813.4 days ago) I have a 3 yr old, a 10 yr old and a 15 yr old. I have it all, lol. And there isnt one harder then the other. They all have challanges and make some days good and some days bad. My first was a VERY hard infant but great toddler, my 2nd was a GREAT infant and a HARD toddler. My 3rd is a mix since he is autistic. The HARDEST part is sibling relationships if you have more then one. The arguing that goes on between my 15 and 10 yr old far outweighs the hard parts on me individually. If I wished my teen was younger or my youngest a teen I'd have a hard time deciding since both are hard at times. EditDelete
