I exclusively breastfed and found it relatively easy to do so.
I
did go though a VERY stressing phase where my MIL,my mum and even DH tried to convince me that Noelia would stop crying so much if we gave her a bottle at night.She was 3 months old and had colic,and I was so sleep deprived that I listened to them and tried it for
4 nights.
I HATED it.I felt like I was depriving her of her most comforting nursing session (she loves to nurse to sleep) so after just 4 nights,I refused to do it again and went back to exclusively BFing her.
Thats the only time shes ever had milk that wasnt mine,and Im so glad I never did it again.
Apart from those 4 nights (or 4 bottles) I BF her exclusively for over 6 months and we are still BFing now at 18 months
BFing wasnt/isnt difficult for me.That part was/is easy.Noe was a VERY needy NB and she cried ALOT,so what made me make the mistake of feeding her a bottle for 4 nights wasnt the difficulty of the act of BFing,but the fact that she was always so incredibly fussy and I was too tired to give in to all the pressure I was under.
Of course,once I realised that the bottle wasnt the solution,and I felt guilty for not nursing her to sleep,I put a stop to it right away.
