Hello Everyone I didn't realise breastfeeding ...

Hello Everyone I didn't realise breastfeeding would be so hard but I have stuck it out for this long (our little girl has one bottle of formula a day) My MIL though only being helpful asked if our little girl would be more settled on formula! She is still waking a couple of times at night to be fed and most of the time will go back to sleep no problems its just during the day when she gets quite unsettled and doesn't really have a sleeping routine as yet (she does have to fit in with her 2 year old brothers routine so it makes it hard) I was hoping to fed her until 6 months but am really starting to question whether I should switch her now the screaming during the day (whilst I know babies cry) does get quite annoying thanks melly
