I have been giving my 8 week old DS pre-made Aptamil first formula since he was 3 weeks old.
He suffers with reflux and is on gaviscon for this which does help alot, along with keeping him upright and having everything tilted!! My HV has advised that I need to move him off the pre-made formula on to powdered formula as otherwise he will end up with a 'lazy bowel'. I've tried to do my own research on this and have not come up with anything tbh.
My concern with moving him across to powder formula is that he may well become constipated because of the gaviscon and I think that the pre-made formula is actually keeping him regular.
I'm thinking once this hot weather is done and dusted (and DS's crankiness goes away!) to try and introduce the powdered formula slowly over a few weeks - does this sound like a good idea??
