I'm looking for advice/opinions. All advice is welcomed - it will just give me more things to mull over. So basically since my daughter was born (over 5 weeks ago) we've been on a bit of a rollercoaster in regards to breastfeeding.

Basically the first week I was breastfeeding her, she didnt latch properly so she began to lose weight. I tried expressing milk and feeding her with a cup, but the first time I did that, she decided she wanted absolutely nothing to do with the breast. So for the next 1.5 weeks I was pumping and bottle feeding her. Until 2 weeks ago, I offered her the breast with a nipple shield and she latched. We have been exclusively nursing since then. I been to see the lactation consultant many times and they do think she has a small Tongue and lip tie, but it is minimal, and I dont want to get them clipped.

Now, the issue is, since she was born, we have struggled alot with extreme fussiness. She basically cries constantly when she is awake. It is nonstop. She will be awake from 8 in the morning to 12 at night, and cry the entire time unless shes nursing her having like a 10 minute cat nap. It got even worse this past week to the point of her just seeming completely and utterly miserable. I finally decided to take a break from nursing and for the past day I have been feeding her formula while pumping every 3 hours and freezing my milk.

Since her second bottle of Formula, she has begun to act like a complete and total different baby!! She is happy! She sleeps! Like dead to the world, I can move and change her without her waking up. She has been having wakeful periods of up to an hour without crying at all!!! Like this changed my baby completely.

So now I am so confused If I should continue with formula or go back to breastmilk. What was it with my breastmilk that was upsetting her? Was she not getting enough milk? I've been pumping every 3 hours and only get 2oz total when I do. Or could it be a milk allergy? The formula I'm using is Similac Sensitive. The other thing I've considered, is could it be like a hindmilk/foremilk imbalance?

All I do know is that for the first time since my baby has been born, she is happy and content.

I want to breastfeed so bad ... but I also want her to be happy. I'm at loss of what to do.
