I am tandem feeding my 5 week old and 18month old DDs. All seemed to be going really well initially, but at 3 weeks DD2 stopped pooing frequently and changed to every 2 days, then went for 6 days without a poo, currently no poo or 7 days.
She was seen by HV and GP, as she seemed fine, weeing plenty, putting on weight, and poos were normal when she does go they weren't worried.
HV came today (to see how jaundice was - still jaundiced last week but that's now gone) and DD2 hasn't gained any weight since she was last weighed 6 days ago. She's also seemed a lot more unsettled than normal since saturday night, and last night I ended up taking her to OOH GP as she seemed unwell and had a temp of 38.1. Temp had resolved by the time GP saw her so he checked her over but thought there was nothing to worry about.
HV is coming back on friday, and I'm worried that if problems not resolving then its going to be the tandem feeding that gets the blame. DD2 feeds every 2-3 hours during the day and 3-4hrly overnight. Generally her latch seems good - I've never had any pain feeding her although she seems to be having more trouble getting latched on properly today and its taking a few attempts to get her on and staying on. DD1 feeds little and often at the moment - approx a minute at a time about 6 times a day.
Would be really grateful for any suggestions on how to help DD2, am feeling quite worried about her. DD1 always gained masses of weight so am feeling a little out of ny depth here.
