Would a 6 week prem baby have growth spurts / development leaps at his current age and also corrected age? He is now 9+4 weeks so 3+4 weeks corrected and we seem to have been having a nightmare time since around 6 weeks. I read somewhere that they are due rough patches around 3 weeks and between 6 and 8. Just want to know there is an end in sight! He has gone from wanting to feed constantly to refusing to sleep in his bed to eventually going 3 hours between feeds but taking 1-1.5 hours to feed and settle and now being super clingy during the day. Thank you
