Does anyone know if there is a growth spurt around 17/18 weeks? I just can't fill my formula fed baby enough. He was taking 7oz bottles every 4-5hrs now I'm feeding 5oz every 2hrs (so more milk overall). 2 weeks ago he was rejecting feeds and suddenly earlier this week BAM he's constantly wanting feeds. I can't even get him to nap without him waking hungry. Needless to say he's up at night. Last night he had 11oz before bed, woke 3hrs later and had 10oz, took ages to settle (back down at midnight), then he woke at 4.30 for 4oz..That's 25oz in one night! It's wearing me out!
My 18 week old BF baby is the same - so hungry and not sleeping well. He fed almost constantly between 4am and 7am... It's so tiring, especially when sleep had just started to get better. Naps in the day have gone haywire too. He has definitely got taller and changed a lot in the last few weeks though. Not sure what to do aside from roll with it... Maybe they're getting ready for solids? Do you have someone to share the night feeds with?
