Hi,
I really sympathise with your situation. My second daughter, Ellie had a bad reflux problem ever since she was born. She had to have 3 or 4 bibs on at a time, and even then that never soaked it all up. This would happen from the moment she finished her bottle until 3/4 hrs later when she was ready for her next. At first they said she would grow out of it, but when her growth was going down the centile chart, she was referred to the Sick Kids Hospital in Edinburgh. The consultant prescribed her infant gaviscon to put in every bottle of formula. At first, it worked marvellously and she only had the usual possetting after a feed. Then about a month later it all started again. Another trip to the Sick Kids and she was sent for a barium meal just to check there were no blockages anywhere. You can imagine how difficult it was giving a 3 month baby the gloop that had to be taken so that her digestive tract would show up on the x-ray. Anyway, nothing was found and we were told just to continue with the gaviscon, even though it was no longer working.
All i can say is hang in there and it does get better. As soon as Ellie started to sit up and spent more time in a upright position it helped. The introduction of solids also helped. She eventually grew out of it at around 8/9 months.
I would suggest you refrain from putting your lo in a horizontal position as much as you can. A pillow under the mattress of the cot just to elevate a little helps and sitting in a bouncy chair too.
Good luck and happy washing!!!!
