Hi, I did basic GF routine with DD1 (without the expressing) and it worked brilliantly. With DD2 it took me a bit longer to work out how to fit it all together with D1's schedule (she had just turned 2), but here's a summary of the early days if it helps..... All timings fairly approximate of course but based on the ideas behind GF routine, which worked for me and the girls.
My main aim was to try to fit feeds for DD2 in at times when DD1 was busy as she'd get bored and jealous if I was feeding too much. When I was feeding I'd always set up distractions for DD1, i.e. set her up with toys / lego / jigsaws, but have a snack and drink to hand so when she was bored I could give that to her and also have books to hand so she could sit next to me on the sofa and I'd read to her and CBeebies on standby in case all else failed!
7am: get DD2 up and bf her (usually in bed with me).
7.30: DD1 usually woke up around this time and came through and got into bed with me too and had a beaker of milk while I finished the feed.
9 / 9.30am DD2 would nap. If at home this would usually be in moses basket in her room, but might also be in buggy or sling if I was e.g. taking DD1 to playgroup or to a friend or something.
10.30 (pushed out to 11am when a bit older), bf DD2 - worst feed of the day as DD1 bored and wanting attention.
12pm DD2 into bed (in moses basket in her room).
12.15 ish give DD1 her lunch
12.45 ish DD1 into bed (I was lucky she was still napping).
2pm: get DD2 up and feed her.
2.30pm get DD1 up.
DD2 usually had a short nap (buggy / sling / or carry cot sometime in the afternoon, but I didn't really structure this nap as we were usually out and about doing something with DD1).
5.15 pm / 5.30pm give DD1 her tea and bf DD2 one side while sitting at the table with DD1.
6pm: bath them both together (DD2 in plastic bath support so I could have hands free). DD1 would get in first then I'd undress DD2 pop her in quickly and wash and take her out and have time to dress her etc while DD1 played in the bath.
6.30pm ish DD2 into bouncy chair while I read stories to DD1 (rocking bouncy chair vigourously with foot!).
7pm DD1 into bed
7pm final bf for DD2
7.30pm DD2 into bed.
Whatever happened re feeds in the night I always tried to get DD2 up at 7am and get the first bf done before DD1 woke up.
DC3 due shortly - help..........!!
