Hi everyone, My 9 wk old has been on formula since day 4. She started on s26 gold, then tried Karicare comfort, Soy & now De-Lac. She has really bad colic! I was on soy as a baby & cant tolerate much dairy so I thought she was like me... she started to show some signs of slight improvement however after her vaccines at 7 weeks she became constipated & even worse for the following 3 weeks till now. So we made the switch to Karicare De-Lac. Shes been on this for 3 days, first 2 days she was much happier but pooed once a day & fed every 2-2/12 hours! at night she was waking up every hour & half. By day 3 (now) she is really upset. She screamed from 2.30pm to 10pm!!! yesterday I was going mad. She screams as she poos and its deep green and clay consistency. She was even crying thru some feeds. Is it worth swapping her to s-26?? I wasn't sure if it was just her adjusting to a formula change.. Also I have a appt to see a ped oct 30 which im hanging out for, im hoping she can give me answers!
