Read that there's a growth spurt around 8-9 months. Was there one for you? My little one has changed so much in behavior, he won't let me go anywhere, doesn't want to go for walks outside, and doesn't want to sit with his dad and grandma either) Maybe max 5 minutes if they interest him, then crawls looking for me He struggles to fall asleep In general, my brain is about to explode ?
