It’s getting harder

Does anyone else feel like motherhood is getting harder and more tiring all the time? I had such a calm cooperative newborn and now he’s this frustrated ball of energy that will never relax. Just turned five months and spends most of the day on the floor turning to his tummy and failing to turn back again. And I’m feeling guilty for all the bad habits such as feeding him to sleep and not having a proper routine. No family around so no breaks apart from when my SO watches him and even then I’m worrying and can’t properly relax. Guess I’m just struggling right now. 💤
