Hi, any l advice welcome! My 5 week old has this past week transitioned to formula bottles as my breast milk didn't seem to agree with him. He currently has 5oz every 3-4 hours and sometimes leaves an oz. He then has a wake window of 45 minutes to 1hour 15 by then starts to show signs of tiredness. He then fights his sleep so much and is so fussy it makes me so stressed. Should he be sleeping after his bottle? Is his wake window in the right place? I have a toddler too so it's so much harder spending up to an hour trying to get him to nap and then feeding again not long after. Thank you.
