This is my very first time posting here so I hope I am doing this right...
My 5 month old twins (in two days) used to take their naps without too much problems. Especially with my daughter, which is pretty much an angel, everything was smooth sailing so much so that we would impress our guests with our napping routine... we would notice the sleepy signs, she would take her pacifier, be rocked a little and then put in bed and that was the end of it. My son was a little more complicated in that he would need something to "focus on" when in bed and every 3-4 days it would have to be different... a rubber duckie, a book, etc. If we were missing the cues and he would get overtired, he would easily agitated in bed (moving his arms up and down frantically) so sometimes I would have to sing to him to calm him down. Anyway, for several weeks things were more or less under control, especially with my Daughter. Now it's been a whole week where it seems that everything is going crazy. They look tired but when they get to bed they complain and I spend hours trying to calm them down. typically this involves giving them the pacifier after they pull it out with their little hands, singing if they get agitated, picking them up if they get very upset, wondering whether I put them in bed too early, etc.
They used to go down for their naps every 1.5-2 hours but now, even though they seem tired after 1.5 hours, they would still stay awake for another hour or more. Maybe it's just normal for their age but dealing with two fussy babies at nap time (3+ times a day) is a nightmare. I am just trying to set some sort of routine (and coincidentally they seem to be more fussy since I started this?): They get 6 bottles a day (190 ml for Jaco and 160 ml for Sofia) and solids 2 times a day; they get up anytime between 5 and 7 am - this makes it a little hard to have a routine but it's coming together. Their naps used to be at around 8, 11 (in the stroller usually), 2pm and 5 pm. but now it's impossible to put them down to sleep at 2pm and they might stay up until 3 or 4pm and they might have a short nap at that point so that they get totally overtired. Bedtime is at 7-7:30 if they don't get the last nap at 5-ish, 8pm if they do get a catnap in the late afternoon.
Sorry for such a long post... if you can shed some light on what's going on with my kids I would highly appreciate it.
