And they're finally sleeping! Por fin se duermen!

So, recently my kids, Daniel and Alin, don't want to go to sleep at night. I don't know how to convince them that they need to be in bed at a certain time, as we have never had structured bedtimes or naptimes. It has always been that as soon as they are tired, they go to bed, unless we (the parents) are tired first and then they go to bed as soon as we do. This has started to be a pain in the neck, especially during the summer, because they want to be up since it is still light, and Marcelo has to be up by 5:30 am to be to work by six, and when they don't want to sleep until at least eleven, it makes for a rough time! They just quit talking about 2 minutes ago, which means that at least one is asleep... Alin hates to stay in her bed, but since we took the crib out of their room she has to sleep on a normal bed- and there is no way for me to keep her in! It is so frustrating, and i don't know what to do about it. If you have any ideas, please let me know!

Recientmente mis hijos, Daniel y Alin, no quieren dormir de noche. No sé convincirles que necesiten estar en cama a cierta hora, siendo que nunca hemos tenido una hora exacta para acostarse, ni tampoco para las siestas. Siempre ha sido que tan pronto que tengan sueño, se acuestan, al menos que nosotros, sus padres, estemos cansados primeros, y si es asi, se acuestan a la hora que nosotros lo hacemos. Eso ha empezado a ser un dolor de cabeza, especialmente durante el verano, porque quieren estar de pie mientras haya luz, y Marcelo tiene que levantarse antes de las 5:30 de la mañana para llegar al trabajo antes de las seis, y cuando ellos no quieren dormir hasta pasado las once, hace problemas! Apenas dejaron de hablar hace unos dos minutos, lo cual significa que uno o el otro esté durmido... A Alin no le gusta quedarse en la cama, pero suendo que le sacamos la cuna de su cuarto, tiene que dormir en una cama normal, y no la puedo mantener en su cama! Me frustra tanto, y no se que hacer... Si tienes soluciones, favor de avisarme!
