I return to work when DD is 10 months, initially I will be full time while DH uses his parental and LSL leave so will be working 5 days.

I plan to continue BF morning, evening (and most likely night if DD wants it), but DD will most likely want 1-2 feeds during the day (I will be leaving at 740am, returning about 450pm) and plan to feed her just before I go, and as soon as I return, but she currently has a mid morning and mid afternoon feed, and may be down to one daytime feed by then (I think DS dropped to one just before he was one). Although I plan to pump, I can usually only get 120mls tops if a miss a feed or two, so could mix feed with formula to make up any short fall if needed.

But would 10 months be to early to just use cows milk if she wants another feed and there isn't enough EBM? From what I've read the main issue is that there isn't as much iron in cows milk as there is in BM/Formula - however, if its only one feed per day would it matter? DD already has cows milk in her weetbix so has it in her diet, and is on three meals a day - Weetbix/Porridge etc for Breakfast, then fruit, homemade custard and/or yoghurt for lunch, and vegies and meat/chicken or fish for dinner - she eats a decent serve (eg about half a toddler bowl full, she has a good appetite for solids) so I am thinking with the continued BF when I am home, the solids etc she'd be getting enough iron so 1-2 bottles of cows milk shouldn't be an issue iron wise?

Is there anything else I need to consider from a nutritional perspective - or should I just have formula as back up for the 2 months until she's one?
