Breaking Lockstep

Today, I took J to the dentist to get her newly erupted adult molars sealed. While she was in the capable hands of the dental assistant, M and I sat in the room and read silently.

J is helping out at the dentist.

This sort of this is the norm for many families; while one sibling is involved in a procedure or activity, the others have to wait it out. For us, though, this is new. All our twin daughters’ preventive care and major milestones have come on nearly identical schedules. They crawled within a week of each other and both walked within a month of their first birthday. They both needed speech therapy, progressed through it together, and graduated on the same day. They have matching cavities.

J, however, now has her first molars, and M doesn’t. They have intensely different personalities, but I can’t help thinking that this divergence in their dental schedule marks a shift from the lockstep development timeline they’ve shared thus far.

Do your multiples reach milestones around the same time? Which ones?

Sadia’s identical daughters, M and J, are 6-year-old rising second graders in El Paso, TX.

  1. Mine have done almost nothing at the same time. Never. Joshua has been behind on everything and has needed the extra help. But it could be because I’ve got a girl and a boy. Girls seems to develop faster in so many ways. That said, I’m completely loving this stage they are now in at 3,5yrs. With their own interests and desires, ideas and the amazing imagination life is never dull here as they each reach their own developmental stages.

  2. Interesting. My kids are not identical, but just like yours they have met their milestones within a few days of each other. But the teething process has them breaking the sync – Apple developed her adult molars first and had her lower 2 teeth fall at once 3 weeks ago and Angel has started sprouting her adult molars now. I am thinking it will be atleast 3 weeks more before her teeth begin to fall out.

  3. my girls are identical and both have reched milestones at the sme time so have my other set of IDs my younger set annie and abbie are 6 and a half and did it all at the same time thay took ther first step together,said thr first word on the same day,got ther first chek ups and cuts and lost ther first teeth on the same day it was the same with my older girls sara and sofie thay both had ther brases off the same day,got ther first toddler beds together and got ther molers within 2 days of ech other.

  4. My girls have reached all their milestones within a day or so of each other. Every step, every tooth, and every word. It’s freaky and part of the reason I don’t think they are fraternal (at least not completely).
