Your twins are going to be behind socially perhaps physically because you can't let them out of stroller?!?!
Mine are 22m and I also have a 3yo. I never have help, therefore, can't go to parks, can't go to swim or to the beach or let them out in any play area. Nothing is fenced in! I feel like they are always in their stroller not getting to explore and play. Makes me sad and worry a bit! I really need a nanny
Re: Do you ever feel like...
I do have this thought occasionally! I know that my girls spend far more time in a stroller than my son did. Have you tried going to the park? I was really scared to try it solo, but I found that it's doable. I have to pick my playgrounds with care (no mulch for the little ones to eat, smaller structures that they can climb on, no structures far away that my 3 year old would be drawn too). It's a workout and certainly not a mental break for me though!
We also spend a lot of time outside at home, because that's the easiest place for me to keep track of all three.
TTC since May 2006. After 3 failed Clomid cycles, 2 failed Injectibles/IUIs, 2 failed IVFs and 1 failed FET, we moved on to adoption!
Last ditch FET resulted in BFP, and identical twin girls!
