My 9.5 week old (gosh it goes so fast!) is cluster feeding in the evening and sometimes afternoon. Feeding does not bother me too much but the on /off fussing / grumpiness is difficult especially as I have an almost 2 year old and my husband is not getting home from work till 7 ish. When does the fussing end?? With my toddler or was 12 weeks ish. Is it true for all!?? Would you give a bottle during this time? Thanks
