My LO just turned 4 months old and outta no where became impossible to get to nap. He sleeps through the night for the most part waking up at 6 am the earliest and sleeping by 7, but getting him to nap is so hard. And by the end of the day he is so tired and cranky which makes it even more frustrating to get to sleep/nap. He has reflux so sometimes I think maybe he's just uncomfortable but I really just think he fights it. Therefore, I have a fussy cranky baby all day. Any other moms going through or went through something like this with their babes around this time?? It worrys me he's always been such a good sleeper and player and so happy it's hard on a FTM! Any advice or words to help me through this with him!?
