Is the reflux and CMPA being managed?
My ds was exactly as you describe for the first 3 months, and I have a 2yo dd, and it got to the point of me sitting in my underwear (no clean clothes left from reflux vomit) hysterically bawling my eyes out as ds was sick on me again to finally reach breaking point.
1- I told dp everything, that sometimes I handle him too roughly because im so angry, sometimes I just want to leave him in a shop and walk away, sometimes I just put him in the furthest room from the living room screaming and shut the door and have a cuppa tea..... Just getting it out helped.
2- I called a lady who I didn't know very well but I had met at church and had mentioned her dd had a CMPA and reflux, she came round with a massive bag of clothes she didn't need anymore and told me that she would be round twice a week to pick up and drop off washing (I was washing every day and couldn't keep on top of it all)
3- I gave myself a pat on the back, because you know what? The little baby your looking at is alive because of you (and if your breastfeeding even more so!)
Your doing a great job, call in any and all favours. If someone mentions 'if I can help just let me know' follow it with 'well, actually, we are really struggling with....' Instead of 'will do! Thanks!' Because everyone knows that they never follow it up!
Medication can help with reflux, ds is on ranitadine (now 7mo) and a special formula called Nutramigen which is for CMPA. He's like a different baby!
Your doing a great job, and you've taken a massive step by going to the drs! Once you've found a supportive Dr try to only see them, it really helped me feel like I could talk to them
