Russell is now just over four weeks old and we have just passed the date he was due to arrive. For an early baby he is doing very well. He is already drinking much more milk than Penny was at this stage and weighs a great deal more having reached over 7lbs. He currently feeds at hourly intervals and is still on a mix of expressed milk and being breastfed. I do wonder how long it will be before I need to start supplementing his feeds with formula. Looking back I started doing this with Penny at around 3 months old before switching her completely towards the 6 month mark. Russell is altogether a much hungrier and demanding baby but it would be nice if we can manage breast milk for at least the first couple of months.
