First time mum. Baby breastfed and bottled at night until I could not fill her. Went onto aptimil and she suffers shocking from tummy ache and bad wind. Sleeping for 2 hours in between feeds. Tried hungry baby. .no change. Tried level 2 teets. No change. Aired water.. infacol.. gripe water... nothing is helping and I can tell she is in agony and she is such a happy baby when no tummy ache! I feel helpless. What are people's experiences with aptimil comfort? Hv got me Gaviscon but the issue is het bott half not top. Any advice welcome please x
