Hi Lindsay,
I wanted to reply in case anyone comes across this thread looking for help in the future and also to thank you.
The last week has been a struggle and we have persevered
I'm so happy to report that we have successfully pushed to three hours of A time. Yay! Whoop Whoop! We learned that once we helped him push through his initial sleepy/fussy phase that seemed to come anywhere between 2/2.5 hours, all would be OK. I usually nurse him at that time and we are starting solids this weekend as well. He's been going down for naps pretty well and *most* of the time we can get over the 45 minute hump for a decent nap. Either way, he wakes up happy! Cat naps are not even worth the struggle or stress for us anymore and we plan on bedtime from anywhere between 7pm and 8pm; we schedule accordingly from the time he wakes up from his second nap.
We have had some night wakings throughout this period and are going back to sleep training/reducing the amount of time he is nursing each night. We did this before and it worked great with him sleeping through the night again after just a couple of nights.
Thank for your encouragement and support! I read my last question and felt like such a goober. In the throws of these changes, when you are OT yourself as a mommy, you sometimes just feel so desperate and unsure of yourself.
