My lb is 4m and is ff. In Scotland were in the 30s and its really really hot. My lb sweats a lot on a normal day never mind this heat and I was told by my HV I could give him some cooled boiled water, but how much in one day? My HV isn't working today and the office closes at 4pm and I haven't been able to get a hold of anyone else. I bought some hipp organic baby juice for 4m+ too but again have no idea how much I can give him on days like this...
