I don't know what's been up with brendon this past week, he was doing so well at night only waking up once at 4 to be fed. But since Monday bedtime it's been a nightmare! He's gone from going to sleep at half 6 to still being awake and screaming at half 8 now, he's waking nearly every hour and he's eating so much more during the night, it's like he's a newborn again 😥 no idea if it's a growth spurt or teething 🤔 I just want some sleep!
